1️⃣ Preheat the oven

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish and set aside.

2️⃣ Cook the pasta

Boil the elbow macaroni in salted water according to package instructions until al dente. Drain and set aside.

3️⃣ Prepare the meat mixture

Heat a large skillet over medium heat. Brown the ground beef, breaking it up into crumbles as it cooks.

Add the chopped onion and cook for 3–4 minutes or until softened. Drain any excess fat from the skillet.

4️⃣ Add the seasonings

Stir in the cooked, crumbled turkey bacon, ketchup, mustard, garlic powder, onion powder, salt, and pepper. Let the mixture simmer for 5 minutes to blend the flavors.

5️⃣ Combine with pasta

In a large mixing bowl, combine the cooked macaroni with the beef mixture. Pour in the milk and stir well to coat everything evenly.

6️⃣ Assemble the casserole

Transfer the mixture into the prepared baking dish, spreading it out evenly. Sprinkle the shredded cheddar and mozzarella cheeses evenly over the top.

7️⃣ Bake

Bake in the preheated oven for 20–25 minutes, or until the cheese is melted and bubbling.

8️⃣ Cool and serve

Let the casserole cool for a few minutes before serving. Enjoy the cheesy, hearty goodness!
