This hearty, family-friendly casserole combines seasoned ground beef, tender macaroni, colorful bell peppers, and melty cheddar cheese into one easy and comforting bake. Perfect for busy weeknights or potlucks!
Cook the elbow macaroni according to the package instructions, drain, and set aside.
In a large skillet, brown the ground beef over medium heat until fully cooked, breaking it into crumbles as it cooks. Drain excess fat.
Add the chopped onion and bell peppers to the skillet and cook until they are tender, about 5 minutes.
Stir in the garlic powder, onion powder, diced tomatoes with their juice, salt, and pepper. Let everything simmer together for about 10 minutes, allowing the flavors to meld.
In a large mixing bowl, combine the cooked macaroni with the beef and vegetable mixture. Stir in 1 cup of the shredded cheddar cheese.
Transfer the mixture to a greased 9x13-inch baking dish. Sprinkle the remaining cheddar cheese evenly on top.
Bake for 20 minutes, or until the cheese is melted and bubbly. Let it cool for a few minutes before serving.
Notes
Make it your own by swapping the ground beef for ground turkey or adding in some corn or black beans for extra texture and flavor. Great for leftovers too!
