Preheat oven to 375 degrees F.

In a medium saucepan, cover potatoes and crushed garlic with enough water to cover by 1-inch. Add some salt and bring to a boil over high heat, then reduce to medium-high and cook until fork tender, about 15 minutes. Drain potatoes, return to pot, and mash together with 3 tablespoons of the butter and the heavy cream. Season with salt and pepper, to taste, and set aside.

In a large pan on medium-high heat, combine 1 tablespoon butter and 1 tablespoon oil. When butter has melted, add beef, Worcestershire sauce, cayenne pepper and salt and pepper, to taste, and cook until meat is brown. Stir in tomato paste and saute for a few minutes. Add stock and bring to a simmer. Season and remove mixture to a bowl. In the same pan, add remaining butter and oil and saute onions until almost tender, then add red bell pepper, zucchini, carrots and paprika. Cook until tender, about 10 minutes. Remove from heat.

To assemble, in a 9 by 12-inch baking dish layer half of beef, pressing down to pack in, then sprinkle the cheese on evenly. Pour the remaining half of the beef over the cheese and press down. Next, add the sauteed vegetables and top with the mashed potatoes, spreading out with a spatula or the back of a spoon to even out and to form decorative peaks and valleys. Sprinkle top with paprika and bake for 30 minutes or until edges on potatoes turn golden brown. Serve with Mushroom Onion Gravy.

Mushroom Onion Gravy:

In a medium saucepan over medium heat, saute onions and mushrooms in oil until tender and mushrooms release their moisture, about 5 minutes. Add flour and stir to evenly coat. Slowly whisk in wine and then the broth. Simmer until thickened and season with salt and pepper, to taste.
