Collard Greens Gratin
- 8 ounces bacon, diced
- 1 cup sliced baby portabello mushrooms
- 3/4 cup diced red onion
- 2 bunches collard greens, rinsed, deveined and cut into 1/8-inch wide strips
- 1/3 cup butter, plus more for greasing pan
- 1/3 cup all-purpose flour
- 2 1/2 cups heavy cream
- Salt and ground black pepper
- 1/2 to 3/4 cup grated Asiago
- 1/2 cup french-fried onions
Preheat the oven to 350 degrees F.
In a large saute pan, fry the bacon until half-cooked. Add the mushrooms and red onions and saute until the bacon is fully cooked and onions have softened. Increase the heat to high. Add the collard greens and cook until the greens are wilted. Turn off the heat and set the pan aside.
In a separate pan, melt the butter and then add the flour. Cook, whisking frequently, to create a smooth, blond roux (this will take 3 to 4 minutes; do not brown, as the goal is just to remove the raw taste from the flour). Slowly add the cream while whisking and adjust the heat to keep the sauce at a simmer. Add the salt and pepper to taste (it should taste like a moderately salty cream gravy). Continue cooking until the sauce thickens and easily coats the back of a spoon.
Butter an 8-by-12-inch casserole dish (or 8-to-10-cup capacity casserole). Combine the collard greens with cream sauce and transfer to the casserole. Top with the cheese and french-fried onions. Bake, uncovered, until the cheese begins to brown, 15 to 20 minutes.
