How to Make Low Fat Ground Beef Casserole

1. Preheat oven to 375°F (190°C). Lightly spray a 9×9-inch baking dish with nonstick cooking spray.
2. Cook the beef and onions in a large skillet over medium heat until the beef is browned and the onions are soft, about 7 minutes. Drain any excess fat.
3. Add garlic, spices, diced tomatoes, and tomato sauce. Stir well and let simmer for 5 minutes to meld the flavors.
4. Mix in the cooked pasta and remove the skillet from heat.
5. Combine cottage cheese and Greek yogurt in a small bowl. Stir this mixture into the pasta and beef mixture.
6. Transfer to the baking dish and spread evenly. Sprinkle shredded cheddar cheese over the top.
7. Bake uncovered for 20 minutes or until hot and bubbly. Let it cool slightly before serving.

Recipe Tips and Variations

• Add chopped spinach, zucchini, or mushrooms for extra veggies.
• Swap the pasta for cooked brown rice or quinoa if you prefer a gluten-free version.
• Use ground turkey or chicken for a different lean protein option.
• Want more heat? Stir in a pinch of red pepper flakes with the spices.

How to Store Leftovers

Let the casserole cool completely, then store in an airtight container in the fridge for up to 4 days. You can also freeze portions for up to 2 months. Reheat in the microwave or oven until warmed through.
