Ingredients for Macaroni Beef Casserole

Grab these simple ingredients – you probably have most in your kitchen already! I’ve learned over the years that quality matters here, especially with the cheese and beef. Trust me, splurging on good cheddar makes all the difference.

• The pasta: 1 lb elbow macaroni (cooked al dente – don’t overcook it!)
• The beefy goodness: 1 lb ground beef (80/20 works best), 1 small onion (finely diced), 2 cloves garlic (minced)
• For the creamy sauce: 2 tbsp butter, 2 tbsp all-purpose flour, 2 cups whole milk, 2 cups shredded sharp cheddar (divided)
• Flavor boosters: ½ tsp paprika, ½ tsp Italian seasoning, salt & pepper to taste
• Optional but pretty: Fresh parsley for garnish

See? Nothing fancy – just real ingredients that come together to create magic. Pro tip: measure everything before you start cooking. It makes the process so much smoother!

Equipment You’ll Need

Don’t worry – you won’t need any fancy gadgets for this casserole! Just grab these basics:

• A trusty 9×13-inch baking dish (glass or ceramic works best)
• Large skillet for browning that beef
• Medium saucepan for the cheese sauce
• Colander for draining pasta
• Wooden spoon – my absolute must-have for stirring

That’s it! Now let’s get cooking.

How to Make Macaroni Beef Casserole

Alright, let’s dive into the fun part – making this cheesy, beefy masterpiece! I’ve made this casserole so many times I could probably do it in my sleep, but I’ll walk you through each step carefully. The secret? Take your time with each layer – good things come to those who wait (especially when cheese is involved).

Step 1: Cook the Pasta and Beef

First, get that pasta going! Bring a big pot of salted water to boil (it should taste like the sea) and cook your elbows just until al dente – about 7 minutes. They’ll finish cooking in the oven, and nobody wants mushy noodles! Drain them and set aside.

While the pasta cooks, grab your skillet and brown that beef with the onions and garlic over medium heat. This is where the magic starts – the smell alone will have your family hovering in the kitchen. Sprinkle in the paprika, Italian seasoning, salt, and pepper. Cook until the beef is nicely browned and those onions are soft – about 8 minutes. Drain any excess grease if needed.

Step 2: Prepare the Cheese Sauce

Now for the showstopper – the creamy cheese sauce! Melt the butter in your saucepan over medium heat. Whisk in the flour and cook for about a minute until it smells nutty (this is your roux – fancy name, simple technique). Slowly pour in the milk while whisking constantly to avoid lumps. Keep stirring until it thickens enough to coat the back of a spoon – about 5 minutes.

Remove from heat and stir in 1½ cups of that shredded cheddar until it’s smooth and dreamy. Taste it – go ahead, I won’t tell! Add more salt if needed. This sauce is what makes the casserole extra special, so don’t rush it.

Step 3: Layer and Bake

Time to assemble! Grease your baking dish lightly. Spread half the cooked macaroni in the bottom, then all the beef mixture, followed by the remaining macaroni. Pour that luscious cheese sauce evenly over everything – I like to wiggle the dish a bit to help it settle into all the nooks.

Sprinkle the remaining ½ cup of cheese on top (because more cheese is always better). Bake at 375°F for 20-25 minutes until the edges are bubbly and the top gets those gorgeous golden spots. Let it rest for 5 minutes before serving – I know it’s hard to wait, but this helps everything set up perfectly.

Tips for the Best Macaroni Beef Casserole

After making this casserole more times than I can count, here are my can’t-live-without tips:

• Rest time matters: Let it sit for 5 minutes after baking – it’ll slice beautifully instead of oozing everywhere.
• Cheese choices: Full-fat cheddar melts smoother, but for extra tang, mix in some Monterey Jack or pepper jack.
• Pasta perfection: Undercook your elbows by 1 minute – they’ll soak up sauce without turning mushy in the oven.
• Brown that beef: Get a good sear on the meat for maximum flavor – pale beef makes for bland casserole.

Follow these, and you’ll have people begging for the recipe!

Variations of Macaroni Beef Casserole

One of my favorite things about this recipe is how easily you can switch it up! Here are some delicious twists we’ve loved over the years:

• Turkey twist: Swap the beef for ground turkey – just add an extra pinch of Italian seasoning for flavor.
• Veggie boost: Stir in sautéed mushrooms or spinach with the beef mixture for extra nutrition.
• Spicy kick: Add diced jalapeños to the cheese sauce or use pepper jack instead of cheddar.
• Pasta swap: Shells or cavatappi work great if you’re out of elbows – anything that holds sauce well!

The possibilities are endless – make it your own!

Serving Suggestions

This Macaroni Beef Casserole is practically a meal on its own, but I love serving it with garlic bread to soak up every last bit of cheesy goodness. A crisp green salad cuts through the richness perfectly. When my kids were little, I’d portion leftovers into individual containers – they made the BEST school lunches reheated the next day (if they lasted that long!).

Storage and Reheating

Here’s the good news – this Macaroni Beef Casserole keeps like a dream! In the fridge, it stays fresh for 3-4 days when covered tightly. For longer storage, freeze individual portions for up to 2 months – just thaw overnight in the fridge before reheating.

To reheat, I always prefer the oven (350°F for about 20 minutes) because it keeps that crispy cheese topping intact. The microwave works in a pinch (1-2 minutes per serving), but expect softer texture. Pro tip: add a splash of milk before reheating to keep everything creamy!

Macaroni Beef Casserole Nutrition

Here’s the scoop on what’s in each comforting serving (but remember – nutrition varies by ingredients!): About 550 calories per serving, with 30g protein to keep you satisfied. You’ll get 50g carbs (hello, energy!), 25g fat (mostly from that glorious cheese), and 3g fiber. Not bad for a dish this delicious! The sodium lands around 600mg – perfect balance for all that flavor.

FAQs About Macaroni Beef Casserole

Can I use a different pasta shape? Absolutely! While elbows are classic, any short pasta works—shells hold the sauce beautifully, and rotini adds fun texture. Just stick to the same weight (1 lb) and cook it al dente.

How long does this casserole keep in the fridge? It stays delicious for 3-4 days when covered tightly. The flavors actually deepen overnight—if your family doesn’t devour it all at dinner!

Can I freeze this cheesy pasta bake? Yes! Freeze individual portions for up to 2 months. Thaw in the fridge overnight, then reheat in the oven at 350°F until bubbly (about 20 minutes).

What’s the best cheese substitute for this ground beef mac and cheese? For a twist, try Monterey Jack for creaminess or pepper jack for spice. Avoid pre-shredded cheeses—they contain anti-caking agents that can make the sauce grainy.

Why does my casserole turn out dry? Two culprits: overcooked pasta (always drain it al dente) or overbaking. Pull it when the edges bubble and the top is just golden—it’ll keep cooking as it rests!
