For the ultimate comfort food, try this extra creamy lasagna recipe. Start by cooking finely chopped onions in a bit of oil, then add ground beef and tomato coulis. Season with salt and pepper to taste. When the meat is cooked through, place some mascarpone in the bottom of your baking dish, cover with a layer of lasagna noodles, then the beef and repeat until all the ingredients are used up. Top with grated gruyere or swiss cheese, and bake for 35 to 40 minutes at 350 °F. The mascarpone is what gives this recipe its unctuous, delectable texture.
