Why You'll Love This Recipe
About the Ingredients
1 lb (450g) ground beef
You can use ground turkey or Italian sausage. If using sausage, reduce the salt.
1 medium onion, diced
About 1 cup. Use a yellow or sweet onion for milder flavor.
2 cloves garlic, minced
Fresh garlic is best, but you can use 1/2 teaspoon garlic powder in a pinch.
1 can (15 oz) tomato sauce
Use no-salt-added if you prefer to control sodium.
1 can (14.5 oz) diced tomatoes, undrained
Fire-roasted adds a nice smoky flavor.
1 teaspoon dried Italian seasoning
Or a mix of oregano, basil, and thyme.
1/2 teaspoon salt
Adjust to taste, especially if using salted butter or broth.
1/4 teaspoon black pepper
Freshly ground is best.
12 oz (340g) egg noodles
You can use any short pasta like penne or rotini.
1 cup (240g) sour cream
Use full-fat Greek yogurt for a tangier, higher-protein option.
1 cup (120g) shredded mozzarella cheese
Part-skim melts well. You can also use cheddar or a blend.
1/2 cup (50g) grated Parmesan cheese
Freshly grated melts better than pre-shredded.
Tips & Tricks
- When freezing, use a freezer-safe casserole dish or a disposable aluminum pan. Cover tightly with foil and label with the date.
- To avoid a watery casserole, make sure the meat sauce is thick before assembling. If it's too thin, simmer it a few extra minutes.
- Don't overcook the noodles initially; they should be al dente (firm to the bite) because they will cook more in the oven.
Pro Tips
Step-by-Step Instructions
1. Cook the noodles
Bring a large pot of salted water to a boil. Cook the egg noodles according to package directions until al dente (about 7-8 minutes). Drain and set aside.
2. Brown the meat
In a large skillet over medium-high heat (350°F / 175°C), cook the ground beef, breaking it up with a spoon, until browned and no longer pink, about 5-7 minutes. Add the onion and garlic, and cook until softened, about 3-4 minutes. Drain any excess fat.
3. Make the sauce
Stir in the tomato sauce, diced tomatoes, Italian seasoning, salt, and pepper. Bring to a simmer, then reduce heat to medium-low and let it bubble gently for 10 minutes to thicken.
4. Combine with noodles
In a large bowl, mix the cooked noodles with the meat sauce and sour cream until well combined.
5. Assemble the casserole
Transfer the mixture to a 9×13-inch baking dish. Sprinkle evenly with the mozzarella and Parmesan cheeses.
6. Freeze or bake now
If baking immediately, preheat your oven to 375°F (190°C). Bake for 25-30 minutes, until bubbly and the top is golden brown. If freezing, cover tightly with foil and freeze for up to 3 months.
7. Bake from frozen
To bake from frozen, preheat the oven to 375°F (190°C). Place the frozen casserole in the oven (no need to thaw) and bake, covered, for 50-60 minutes, then uncover and bake for an additional 10-15 minutes, until the cheese is melted and the edges are bubbling.
8. Rest and serve
Let the casserole rest for 5 minutes before serving. This helps it hold its shape when you cut into it.
Delicious Variations
Vegetarian
Swap the beef for a can of drained chickpeas or a bag of frozen mixed vegetables.
Tex-Mex
Use taco seasoning instead of Italian, and add a can of black beans and corn. Top with pepper jack cheese.
Creamy Chicken
Replace the beef with 2 cups of shredded rotisserie chicken and use cream of chicken soup instead of tomato sauce.
How to Store Easy Freezer Casserole Recipes
