‘Last-Minute Dinner’: Just 3 ingredients. I rely on this way too often.

To keep this a true 3-ingredient recipe, think in terms of ground beef, cheese, and sour cream as your base, and treat any seasonings as optional helpers. For extra flavor without adding carbs, you can mix in dried herbs like oregano, Italian seasoning, or a pinch of smoked paprika with the beef. If you enjoy a little heat, use pepper jack cheese or add a few dashes of hot sauce to the sour cream before stirring it in. For a more casserole-style dish, you can layer in very thinly sliced zucchini or a handful of chopped spinach under the cheese; they’ll soften as the bake cooks while still keeping things low carb. If you’re cooking for a crowd, this recipe doubles easily in a 9×13-inch pan—just add a few extra minutes of baking time. Leftovers reheat well in a covered skillet over low heat or in the oven; they also make a nice filling for lettuce wraps the next day. For a slightly richer version, swap part of the sour cream for softened cream cheese, which gives the bake a thicker, cheesier middle layer.
