Sweet n Sour Sirloin Stir-Fry with Ranch Mashed Potatoes

This is an all American twist on traditional Asian style stir fry. The "special sauce" can be thrown together with items we all have on[ our refrigerator door. Stir things up and try this one out!]

Total Time:
40 min
15 min
25 min

4 servings

  • 1 1/2 pound piece sirloin, 1-inch thick
  • 2 pounds Idaho potatoes, peeled and cubed
  • Salt
  • 3 tablespoons vegetable, peanut or canola oil
  • 2 large red bell peppers, seeded and sliced
  • 1 large green bell pepper, seeded and sliced
  • 1 bunch scallions, cut into 2 to 3-inch pieces on bias, greens and whites
  • 2 cups shelled frozen edamame
  • 3 tablespoons brown sugar
  • 3 tablespoons soy sauce
  • 1/4 cup yellow mustard
  • 1/4 cup ketchup
  • 2/3 cup buttermilk
  • Freshly ground black pepper
  • A few dashes hot sauce
  • Handful fresh flat-leaf parsley, chopped
  • Handful fresh dill, chopped
  • Handful fresh chives, chopped

Pop the meat in the freezer for a few minutes to stiffen it up for slicing.

Place potatoes in a pot and cover with cold water. Bring water to a boil. Salt the water and cook the potatoes until tender, 12 to 15 minutes. Drain.

Halve the steak lengthwise then very thinly slice the meat. Heat the oil in a very large skillet over high heat. When oil wafts smoke and ripples, add the meat and stir-fry until caramelized 3 minutes. Add peppers and stir-fry 2 minutes then add in scallions and edamame for 2 minutes more. Stir together the sugar, soy, mustard and ketchup and pour over stir-fry the last minute of cooking. Season, to taste, if necessary.

Mash potatoes with buttermilk, salt and pepper, hot sauce, parsley, dill, chives, adjust seasoning with salt and pepper, to taste, and serve with stir-fry on top!

    Very good but doubled the sauce and added 1 table spoon crushed wet ginger.
    The best part for me is the sweet and sour sauce. It's quick and easy and made from everyday things I have in the cabinet. I love not having to go to the store to buy special ingredients and I can use it on my chicken when I'm in a hurry to make something quick for my kids. Love it!!! Thanks alot Rachel Ray. ;
    I didn't have the green pepper or the green onion, so I just used the red pepper, a sweet onion, and 2 cloves of chopped garlic. I also added more brown sugar to the sause because I have a picky eater that loves anything sweet. All in all everyone loved it and my husband has requested it to be a weekly meal.
    I personally did not care for this, but my husband loved it. I might make it every couple of months to please him, but I think there are so many better sweet and sour stir fry's out there, especially when you consider the cost of the ingredients. Red Bells where I live can be 1.99 a piece! Also, I could not find edamame so I substituted sugar snap peas.
    I made this recipe tonight for dinner and my husband and I loved it!!!!!!!!!! I had second thoughts after the mixed reviews with the "sauce thing". The sauce was quite good and was very tangy. Lots of Vitamin C with all the peppers and I made brown rice with the dish. Very good and will make again! Thanks Rach!
    Not good. I followed the recipe exactly. The sauce tasted like the ingredients - a mixture of ketchup and yellow mustard. Yuck.
    I just made this meal and it was so delicious! My husband just loved
    it. It was very easy to make and I will be making again, soon.
    Would highly recommend this recipe to everyone. Try it!
    This dish was quite simple to make. I ran to GreenLife after work and grabbed the fresh ingredients. It was done in no time. I changed just a couple of things due to personal preference. I served it over rice that I cooked in chicken stock instead of the ranch potatoes, although I will have to try the ranch potatoes another time. They sounded wonderful. I also added cremini mushrooms to the stir-fry. Next time, I'll make a little extra of the sweet and sour sauce as we like things really saucy.
    Just hearing the ingredients in the sauce can turn you away from this recipe but it is tasty. I served it over noodles and made a more traditional stir fry with red and grenn pepeers, carrots and broccoli. I shared the sauce recipe with my sister and she says it is a winner.
    I didn't try it over the potatoes because it really didn't float my boat for taste buds. I used the stir fry over Basmati Rice and it wasn't anything to write home about, but I was surprised at the flavor of the ketchup, mustard, brown sugar and soy sauce together. It wasn't nasty, but definitely wasn't the greatest either. One of those meals that if you have everything for it and can't think of what else to make with it, give it a whirl. Works decently well with chicken and mixed veggies as well.
    Ok, I have to admit. Sometimes Rachael kind of freaks me out with her off the wall combinations of foods. This time was no different. I saw the show where she made this, and I was intrigued. I'm always looking for a good beef recipe ( I feel bad constantly feeding hubby chicken), and I'm so glad I gave this one a chance.
    The ketchup, mustard, brown sugar, soy sauce sounded beyond gross to me, and I almost didn't make it, but boy am I glad I did.. The sauce was awesome, and once it cooked down, it lost the "ketchup-y" consistency and also gained a great tang with the mustard.
    I didn't used the edamame, (mostly because the only ones in my supermarket where still in their pods and I didn't have the time to fuss with pods!). So, I subbed broccoli for it and it was great.
    I didn't do the smashed potatoes with it, something about stir fry and mashed potatoes didn't seem appetizing. So, I made it with brown rice to up the healthy factor and I had a home run dinner. And, unlike many of Rach's other recipes, this one truly is a 30 minute meal. ( Sorry Rachael, you know I love you but I can't tell you how many times you're "30-minute-meals" have turned into a an hour long production and then some.)
    This has just become my go-to week night meal on a time crunch. Plus, all the veggies and brown rice make it super healthy. And....in response to another comment about this being unhealthy. I guarantee you this is WAY WAY WAY more healthy than anything you will get in a take out box. So there.
    This was a delicious dinner. Like other posts, the sound of the combination of ingredients for the "sweet and sour" sounded very different than any other stir fry I've made. It is and it is delicious! The only changes I made were to season the steak before it went into the hot pan and I added fresh chopped garlic. I also substituted a more "traditional" vegetable stir fry, i.e., julienned carrots, zucchini, red onion, red, green and yellow peppers,instead of the edamame and it was very flavorful. Also served it over the fettucine which another poster mentioned, fabulous alternative to the rice! Great job, again, Rachel!
    My husband and I love steak so this was a winner for us. The sauce ingredients did sound a little odd but worth a try. I served this with brown rice and tofu noodles instead of mash potatoes . I also used a lot more veggies because I am a veggie fanatic. I added fresh green snap peas, red cabbage (as mentioned by another commenter), broccoli (this is excellent with it), and bean sprouts. I ended up getting shallots at the store instead of chives..oops but turned out good anyway. I also used one New York strip steak and one sirloin steak. I think the sauce is great and will make this dish again!!!!
    This is super easy and filling. I serve mine with pasta instead of the mashed potatoes. At first I thought the combination sounded weird, but I was pleasantly surprised. My husband couldn't even guess what was in it!
    Loved the sauce on this...sounded strange but tastes great!
    I have made this sweet and sour sauce with beef, chicken and pork stir fry and it taste great with all. It is so easy to make with ingrediants we always have in the house. I love it!
    Had a great time fixing it, and really enjoyed this meal. Unlike other reviews I really enjoyed the sauce. I thought it added a good zing to the meal. We added red onion to this already great stir fry recipe, and the onion made it that much better!
    I needed something good and something fast. Wednesday cooking time gets cut in half because of needing to leave for church. When I get home, I need something that will not be the same old same old meal. My husband had defrosted the sirloin for Tuesday so I knew I needed to cook the sirloin today. So, I jumped on the food network site in hopes of finding an easy recipe that I had all the ingredients for. THIS WAS IT!! I was uneasy about making it after reading some of the negative reviews but then thought...opinions are like brains...everyone has one. I mixed the sauce and WOW!!! I loved it. I did substitute some of the ingredients as we are diabetic and my husband must watch his salt intake, so I used low sodium soy sauce. I also used steam rice instead of mash potatoes and added frozen peas and fresh cabbage. The whole dish turned out great and even my teenager loved it.

    Just remember people, never not try something just because someone else's taste buds doesn't like it, is stupid. For instance, not everyone likes chitterlings but their are lots of people that do (excluding me).
    Rachael calm down. I am sorry, but some foods are not meant to be combined. Americans really need to move away from the crap that we eat. All the sodium in this meal is enough for 2 weeks and I cannot even imagine what it would take to digest a meal like this without some sort of discomfort. Please, make some foods that are natural and healthy that we can feel good about eating.
    I love Rachael and her recipes, but this one was not good at all. The ketchup, mustard, etc... sauce ruined the dish. It would have been better with bottled teriyaki.
    Great recipe. Hubby and I both enjoyed it. Next time I'll cut out one of the red bell peppers (a little too much peppers for our taste) and add some pineapple. I didn't use the endarme (looks too much like lima beans for hubby) and replaced the yellow mustard and brown sugar with honey mustard and served it with rice. YUMM-O.
    I made this stir fry last night for my boyfriend and I! We both loved the was the sauce complimented the meat and veggies! In stead of making the potatoes, I piled it on top of a whole wheat pasta, like some of the other reviews suggested. I also paired it with the red cabbage that she made on this episode as well! This has been on of the best dishes I've made! So good and so easy!
    I made this with London Broil. It was quick, easy & my family loved it ! The sauce was delicious! I will definitely make it again in the future!
    I am a huge Rachel Ray fan. I make her recipes at least once a week. This is by far the WORST recipe I have ever made. I thought it was odd to put ketchup and mustard in a stir fry dish, but since the reviews were mostly favorable, I thought I'd give it a try. I would recommend you skip this recipe and move on to her other delicious dishes. I just made it and have decided I will eat grilled cheese for dinner instead.
    I needed a quick stir fry sauce. When I did my search on FN I knew Rachel would have a recipe with ingredients that I actually had on hand. I was skeptical and as always added my own twist. I subbed 2 table spoons of splenda instead of brown sugar and added 1 tps of peanut oil. As in the reviews I added spaghetti. It was great. My kids (5 & 7) were disgusted initially, but in the end they ate it all. I will never buy bottled stir fry sauce again either!
    I really liked this meal, but my wife only gave it a "3", so I split the difference. The sauce complimented the meat and veggies well, and it went well over mashed 'tators. Will make again.
    This dish was simply delicious. I substituted fettucine noodles in place of the potates and I feel it made the dish. The brown sugar and mustard mixed just right with the vegetables and meat. I added some minced garlic for some extra zest and was happy I did. Highly recommend this recipe and cannot wait to make it again! Sooo easy by the way!
    This meal was everything I was looking for. Different, filling, fresh. And one of the best comfort foods I have ever had. Thanks Rach! Danielle
    I made the stir fry in less than 15 minutes, super quick. I didn't have edamame so I skipped it, and I served the stir fry over leftover spaghetti noodles. Surprisingly tasty. I'll definitely make it again.
    We saw this on tv and made it the next night! This is so easy to make and super yummy!
