How to Make It (Step-by-Step)
Prep time: 15 minutes | Cook time: 35 minutes | Total time: 50 minutes | Yield: 6 Servings
Step 1: Prep and Preheat
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish so the cheese doesn’t stick to the edges.
Step 2: Boil the Macaroni
Cook the elbow macaroni according to the package instructions in a large pot of salted water. Drain it well and set it aside.
💡 Crucial Step: Cook the pasta just until al dente (still slightly firm to the bite). It will continue to cook and soften as it bakes in the oven, and you don’t want mushy noodles!
Step 3: Brown the Beef
In a large skillet, cook the ground beef over medium heat, breaking it into small crumbles with a wooden spoon until it is fully browned. Drain off the excess fat.
Step 4: Sauté the Veggies
Add the chopped onion, green bell pepper, and red bell pepper to the skillet with the beef. Cook for about 5 minutes until the vegetables are tender.
Step 5: Simmer the Sauce
Stir in the garlic powder, onion powder, the entire can of diced tomatoes (including the juice!), salt, and pepper. Let everything simmer together for about 10 minutes to allow those rich flavors to meld.
Step 6: Mix It All Together
In a large mixing bowl, combine your cooked macaroni with the savory beef and vegetable mixture. Stir in 1 cup of the shredded cheddar cheese until it begins to melt.
Step 7: Top and Bake
Transfer the entire mixture into your prepared 9×13-inch baking dish, spreading it into an even layer. Sprinkle the remaining 1 cup of cheddar cheese evenly over the top.
Step 8: The Golden Finish
Bake uncovered for 20 minutes, or until the cheese is beautifully melted and bubbling around the edges. Let the casserole cool for 5 minutes before serving so it holds together nicely on the plate.
💡 Expert Tips for Success
- Grate Your Own Cheese: Pre-packaged shredded cheese contains anti-caking starches. Grating a block of cheddar yourself ensures a smooth, gooey melt.
- Do Not Drain the Tomatoes: The acidic, savory juice from the canned tomatoes is essential for creating the sauce that coats the macaroni!
- Make It Creamy: If you love an ultra-rich casserole, stir in a can of cream of mushroom soup during Step 6 before baking.
Variations and Substitutions
- The Protein Swap: You can easily swap the ground beef for ground turkey or ground chicken for a slightly lighter version.
- Extra Veggies: Stir in a drained can of sweet corn or a cup of sliced mushrooms when sautéing the bell peppers to stretch the meal even further.
- The Spicy Kick: Add a diced jalapeño or a few dashes of your favorite hot sauce to the beef mixture for a Southwestern twist.
Serving Suggestions
- The Classic Pair: Serve alongside a crisp green garden salad dressed in a light vinaigrette.
- The Garlic Bread: A warm, crusty slice of garlic bread is absolutely mandatory for scooping up every last bit of the cheesy beef.
- Extra Greens: Pair it with garlic roasted green beans or a side of steamed broccoli.
