A yummy ground beef casserole that starts with a box of good ole mac and cheese. Perfect for kids, but we adults love it too!
Ground Beef Mac and Cheese Casserole
This ground beef casserole, made with a simple box of macaroni and cheese, is a weeknight favorite around our house. It comes together easy and bakes in no time. It's also a potluck favorite (double it) because while it's basic, it's well seasoned, flavorful and just good old fashioned comfort food. Nobody will know you started with a box of mac and cheese!
Here's how to make it.
Preheat oven to 350 degrees F. Bring a large saucepan of water to a boil for the macaroni noodles, adding a large pinch of kosher salt. Boil for the lowest time according to package directions, drain and set aside. Reserve the powdered cheese sauce package. Meanwhile, in a large skillet heat olive oil over medium heat, add onion and bell pepper and sauté until tender. Toss in garlic and sauté one minute longer, but to avoid bitterness, do not scorch.
Add ground beef and cook until browned, breaking it up as you go. This is also very good with a ground sausage, or split it and use half of each. Drain off any excess fat from meat mixture if necessary and then return it to the pan. Stir in chili powder and seasoned salt, reserved cheese packet and diced tomatoes. I wrote this to keep it a bit on the milder side for the kids, but I substitute one (10 ounce) can of Rotel tomatoes, undrained, plus 1 small can (8 ounce) tomato sauce for the can of diced tomatoes.
Stir until mixed thoroughly, taste and adjust seasonings as needed; add the pasta.
Butter or spray a 9 x 9 casserole dish with non-stick cooking spray and pour meat and pasta mixture in.
Cover tightly and bake at 350 degrees F for 25 minutes or until heated through. Remove, uncover, sprinkle cheese on top and return to the oven for about 10 minutes longer, or until cheese is melted. Serving suggestion: Add a side salad, green vegetable such as broccoli or green beans and garlic bread.

Preheat oven to 350 degrees F. Bring a large saucepan of water to a boil for the macaroni noodles, adding a large pinch of kosher salt. Boil for the lowest time according to package directions, drain and set aside. Reserve the powdered cheese sauce package.
Meanwhile, in a large skillet heat olive oil over medium heat, add onion, green and red pepper and sauté until tender. Toss in garlic and sauté one minute longer, but to avoid bitterness, do not scorch. Add ground beef and cook until browned, breaking it up as you go. Drain off any excess fat from meat mixture if necessary and then return it to the pan. Stir in chili powder and seasoned salt.
Add the cheese packet and diced tomatoes to the meat mixture, stir until mixed thoroughly, taste and adjust seasonings as needed; add the pasta.

Serving suggestion: Add a side salad, green vegetable such as broccoli or green beans and garlic bread.
Cook's Notes: I substitute one (10 ounce) can of Rotel tomatoes, undrained, plus 1 small can (8 ounce) tomato sauce for the can of diced tomatoes. For a different version, stir in a can of ranch style beans.
Variation: Don't want to use the blue box? Simply substitute 2-1/2 cups of water, 8 ounces of elbow macaroni and 2 cups of shredded cheddar. May also substitute ground sausage for the ground beef, or use half of each.
Taco Mac and Cheese: Add in one packet of taco seasoning, or equivalent homemade.
