Before you start
Before beginning, ensure all ingredients are measured and ready. Dice the red bell pepper into uniform pieces for even cooking. Pre-cook the elbow macaroni according to the package instructions until al dente, then drain it thoroughly.
Preheat the oven to 375°F (190°C) so it is ready for the assembly phase. Having all components prepped beforehand allows for a smooth transition from the stovetop to the oven, ensuring the dish remains warm during the assembly process.

- 1 lb ground beef
- 1 red bell pepper, diced
- 2 cups tomato sauce
- 1 lb elbow macaroni, cooked
- 1 cup shredded cheddar cheese

Instructions
Stovetop Beef Base
- Prepare the beef baseHeat a large skillet over medium-high heat. Add the ground beef and cook until browned, breaking it up with a spoon. Drain excess fat if necessary. Add the diced red peppers and cook until softened. Stir in the tomato sauce and simmer for 5 minutes.Look for The beef is browned and the peppers are soft.Safe temperature 160°F (71°C) internal temperature (ground meat)Tip Ensure the beef is thoroughly browned to develop a deep, savory flavor.
The ground beef should be deeply browned and fragrant, with the red peppers softened and fully integrated into the tomato sauce. The mixture should have a thick, glossy consistency that coats the spoon.
If there is excess grease, it is important to drain it at this stage to prevent an oily finish. The sauce should smell rich and savory, signaling that the base is ready for the pasta.
Assembly and Mixing
- Combine and assembleAdd the pre-cooked elbow macaroni to the skillet with the beef and sauce mixture. Stir well until all the pasta is evenly coated. Transfer the mixture into a 9x13 inch casserole dish, spreading it out in an even layer.Look for The pasta is fully coated in the red sauce.Tip Using warm pasta helps the sauce adhere better to the noodles.
The pasta should be thoroughly combined with the beef and sauce, with every noodle coated in the red mixture. The blend should look cohesive and vibrant in the skillet. When transferring to the casserole dish, press the mixture down lightly to create an even surface, which will ensure that the cheese melts consistently across the entire top during the final baking stage.
Final Golden Bake
- Top and bakeSprinkle the shredded cheddar and mozzarella cheeses evenly over the top of the macaroni mixture. Bake in a preheated oven at 375°F (190°C) until the cheese is melted and bubbling, and the edges are golden brown.Look for The cheese is bubbling and golden brown on top.Tip Keep a close eye on the oven during the last few minutes to prevent burning.
The cheese should be completely melted, with a beautiful golden-brown color on the surface. You will notice the sauce bubbling up from the sides, creating a pleasant aroma that fills the kitchen. The casserole should feel firm to the touch but remain moist inside. Once these visual cues are met, the dish is ready to be removed from the oven and allowed to rest before serving.
Common mistakes
A common mistake is overcooking the pasta before it hits the skillet; ensure it remains al dente as it will continue to cook in the oven. Avoid adding too much liquid to the sauce, as the moisture from the peppers and the sauce itself is sufficient to keep the casserole juicy.
Another error is using a temperature that is too low for the bake, which can result in rubbery cheese rather than a beautifully browned, bubbly crust.
How to tell it’s done
The casserole is done when the internal temperature of the beef mixture has reached 160°F (71°C) and the cheese topping is golden brown and bubbling vigorously. The edges should show the sauce beginning to caramelize slightly, and the entire dish should be steaming throughout.
A quick check with a food thermometer ensures the meat is perfectly safe while the cheese is melted to perfection. Let the casserole rest for 5 minutes before serving to allow the layers to settle.
