I remember the first time I made this cheesy bacon and beef casserole; the smell of crispy bacon filled my kitchen, and my family couldn't wait to dig in. The creamy layers of cheese and tender beef combined with elbow macaroni create a comfort dish that’s always a hit!

What sets this recipe apart is the perfect balance of flavors and textures, with just the right amount of gooey cheese and crispy bacon. It's hearty enough to satisfy and simple enough for a weeknight dinner.

Why This Recipe Works

Rich beef flavor: Using an 80/20 blend of ground beef provides just the right amount of fat, which helps keep the meat juicy and flavorful. During cooking, the fat renders out, creating a savory base that enhances the overall taste of the casserole.
Creamy texture: Combining milk and beef broth results in a creamy sauce that envelops the pasta and meat. I found that this combination helps the flavors meld beautifully, making every bite rich and satisfying.
Cheesy goodness: Shredded cheddar cheese not only adds a deliciously gooey texture but also contributes a slight tang that balances the richness of the bacon and beef. I tested this with both sharp and mild cheddar and prefer sharp for its punchy flavor.
Peas for color and nutrition: Adding thawed peas brightens up the dish visually and adds a sweet pop to each bite. They also provide a boost of vitamins and fiber, making the casserole a bit more wholesome.

Ingredients

What You'll Need

1 lb ground beef an 80/20 blend offers better flavor and juiciness than leaner options.
6 slices bacon cooked and crumbled for a smoky, savory kick that complements the beef.
1 cup elbow macaroni uncooked; it absorbs the casserole’s flavors perfectly while baking.
2 cups cheddar cheese shredded; sharp cheddar gives a rich, tangy flavor that melts beautifully.
1 cup beef broth adds moisture and depth to the dish; choose low-sodium for better control.
1 cup milk helps create a creamy texture throughout the casserole.
1 tsp garlic powder adds an aromatic kick; fresh garlic can also be used if preferred.
1 tsp onion powder enhances the overall flavor with a mild sweetness.
1 tsp salt essential for bringing all the flavors together; adjust to taste.
1/2 tsp black pepper adds a bit of warmth and spice.
1 cup frozen peas thawed; they add color and a slight sweetness to balance the dish.
1/4 cup green onions sliced for garnish; they bring a fresh crunch to the finished casserole.

When making this cheesy bacon and beef casserole, look for good-quality ground beef and cheese to enhance the flavors. I always opt for sharp cheddar for that extra zing, and using low-sodium broth helps manage the saltiness perfectly.

Easy Substitutions

Dairy-free: swap milk for unsweetened almond milk — the casserole will be slightly less creamy but still delicious.
Gluten-free: swap elbow macaroni for gluten-free pasta — the texture will be a bit different, but it will still hold the flavors nicely.
Lower calorie: swap ground beef for ground turkey — this reduces fat content significantly but may change the overall flavor profile.

Step-by-Step Instructions

Prep & Cook

1. Preheat your oven to 350°F — this temperature ensures the cheese will melt beautifully and bubble up during baking.
2. In a large skillet over medium heat, brown the ground beef for 5-7 minutes until it's no longer pink — this step adds depth of flavor that makes the casserole hearty and satisfying.
3. Drain any excess fat from the skillet, as too much fat can make the dish greasy.
4. Add the beef broth, milk, garlic powder, onion powder, salt, and black pepper to the skillet and stir well — this creates a creamy base that will coat the pasta perfectly.
5. Bring the mixture to a simmer, then add the elbow macaroni and stir to combine — simmering helps the pasta absorb those delicious flavors.
6. Cover the skillet and cook for about 8-10 minutes, stirring occasionally until the macaroni is tender — you want it al dente, as it will continue to cook in the oven.
7. Once cooked, stir in the crumbled bacon, frozen peas, and 1.5 cups of cheddar cheese until everything is melted and creamy — the cheese adds richness and pulls all the ingredients together.

Assemble & Bake

1. Transfer the mixture to a greased 9x13-inch baking dish — greasing prevents sticking and makes serving easier.
2. Top with the remaining 0.5 cup of cheddar cheese — this will create a nice, gooey topping that pulls together the casserole.
3. Bake in the preheated oven for 15-20 minutes until the cheese is bubbly and golden — you'll know it's ready when the cheese is perfectly melted and has a lovely golden color.
4. Remove from the oven and let it cool for 5 minutes before serving — this allows the casserole to set a bit, making it easier to serve.
5. Garnish with sliced green onions for a fresh, colorful touch and serve warm — the green onions add a nice crunch and a pop of color to the dish.

Tips & Tricks

The Cheese Melting Secret

Choosing the right cheese can make all the difference in your cheesy bacon and beef casserole. I love mixing sharp cheddar with Monterey Jack for that perfect balance of flavor and creaminess. Sharp cheddar adds a punch, while Monterey Jack melts beautifully, giving you that gooey texture we all crave. Just be sure to grate it yourself instead of using pre-shredded cheese; it melts better and has a fresher taste.

Avoiding the Soggy Bottom

A common mistake I made early on was not draining excess grease from the beef after cooking. This can lead to a soggy bottom on your casserole, which is such a disappointment. After browning the beef, let it rest in a colander for a few minutes to drain off any extra fat. This simple step ensures that your casserole will have a nice, firm base, and no one likes a mushy bite!

Pro Tips

Layer Flavors for Depth: Start by sautéing onions and garlic before adding the beef. This builds a rich base of flavor that enhances your cheesy bacon and beef casserole, making each bite more aromatic and savory. I never skip this step, as it creates a wonderful aroma in the kitchen that sets the mood.
Use Fresh Herbs for Brightness: Adding fresh herbs like parsley or chives just before serving can brighten the entire dish. I love the pop of color and flavor they bring, especially when the casserole is bubbling hot. Just a handful sprinkled on top makes it feel gourmet.
Experiment with Cheese Blends: Mix different cheeses to achieve a unique flavor profile. I often combine sharp cheddar with creamy mozzarella for that perfect melt and flavor balance. Each cheese contributes its own character, enhancing the overall experience.
Batch Cook for Convenience: Make a double batch and freeze half for a busy night. This cheesy bacon and beef casserole reheats beautifully, retaining its flavors and textures. I always keep a portion stashed away for those evenings when cooking feels like too much.
Incorporate Vegetables for Nutrition: Sneak in some finely chopped spinach or bell peppers for added nutrition without sacrificing flavor. I find that they blend smoothly into the dish, and the kids never notice. It's a great way to sneak in extra veggies!

Storage & Meal Prep

Room Temperature

You can keep your cheesy bacon and beef casserole at room temperature for up to 2 hours in a covered dish. After that, it’s best to refrigerate it to prevent any food safety issues.
