Ingredients
For the Beef Mixture:
- 1 pound ground beef
- 1 medium onion, chopped
- 2 cloves garlic, minced
- 1 (10.75 ounce) can condensed cream of mushroom soup
- 1 (10 ounce) can diced tomatoes and green chilies, undrained (like Rotel)
- 1 teaspoon Worcestershire sauce
- 1/2 teaspoon garlic powder
- 1/4 teaspoon black pepper
- Salt to taste
For the Noodle Mixture:
- 1 (12 ounce) package egg noodles
- 8 ounces sour cream
- 1/2 cup milk
- 1 cup shredded cheddar cheese, divided
Let’s Get Cooking: Step-by-Step Instructions
Step 1: Cook the Noodles
- Preheat your oven to 350°F (175°C).
- Bring a large pot of salted water to a boil.
- Add the egg noodles and cook according to package directions until al dente. Don’t overcook them, as they’ll continue to cook in the oven!
- Drain the noodles well and set aside.
Step 2: Brown the Beef
- While the noodles are cooking, heat a large skillet over medium-high heat.
- Add the ground beef and cook, breaking it up with a spoon, until browned. Drain off any excess grease. This step is crucial for flavor, so don’t rush it!
- Add the chopped onion and minced garlic to the skillet and cook until softened, about 5 minutes. Your kitchen should be smelling amazing right about now!
Step 3: Create the Beef Sauce
- Stir in the cream of mushroom soup, diced tomatoes and green chilies (undrained), Worcestershire sauce, garlic powder, black pepper, and salt to the skillet with the beef mixture.
- Bring to a simmer and cook for 5 minutes, stirring occasionally, to allow the flavors to meld. Taste and adjust seasonings as needed.
Step 4: Combine Everything
- In a large bowl, combine the cooked egg noodles, sour cream, and milk. Mix well to ensure the noodles are evenly coated. This is where the “sour cream” in Sour Cream Beef Noodle Casserole really shines!
- Add 1/2 cup of the shredded cheddar cheese to the noodle mixture and stir to combine.
- Pour the beef mixture into the bowl with the noodle mixture and gently fold everything together until well combined. Be careful not to overmix, as you don’t want the noodles to break apart.
Step 5: Bake to Golden Perfection
- Pour the beef and noodle mixture into a lightly greased 9×13 inch baking dish.
- Sprinkle the remaining 1/2 cup of shredded cheddar cheese evenly over the top of the casserole.
- Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly and the casserole is heated through. You want that cheese to be beautifully golden brown!
Step 6: Rest and Serve
- Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This allows the flavors to settle and prevents it from being too runny.
- Serve hot and enjoy! Seriously, try not to eat the whole thing in one sitting. (I won’t judge if you do!)
Tips and Tricks for the Best Casserole
Spice it Up!
Want to add a little kick? A pinch of red pepper flakes or a dash of hot sauce to the beef mixture will do the trick. You could even use pepper jack cheese on top for extra heat!
Cream of Anything
Don’t have cream of mushroom soup? Cream of celery or cream of chicken soup work just as well. Use what you have on hand!
Make it Ahead
This Sour Cream Beef Noodle Casserole is perfect for making ahead of time. Assemble the casserole up to the baking step, cover tightly with plastic wrap, and refrigerate for up to 24 hours. When ready to bake, remove from the refrigerator 30 minutes before baking and bake as directed, adding an extra 5-10 minutes to the baking time if needed. This is a lifesaver on busy weeknights!
Customize Your Veggies
Feel free to add other vegetables to the beef mixture. Chopped bell peppers, mushrooms, or even frozen peas would be delicious additions. Get creative and use what your family loves!
Noodle Know-How
If you don’t have egg noodles, you can substitute another type of noodle, such as elbow macaroni or penne. Just be sure to cook them al dente.
Variations to Try
Cottage Cheese Twist
For a slightly tangier and cheesier flavor, substitute half of the sour cream with cottage cheese. Just blend the cottage cheese until smooth before adding it to the noodle mixture.
Cheesy Goodness
Experiment with different cheeses! Gruyere, Monterey Jack, or even a blend of Italian cheeses would be fantastic on top of this casserole.
Healthier Options
Use lean ground beef or ground turkey to reduce the fat content. You can also substitute Greek yogurt for some of the sour cream for added protein and a lighter texture.
Serving Suggestions
This casserole is a complete meal on its own, but it also pairs well with a simple side salad or steamed vegetables. A crisp green salad with a light vinaigrette would be a perfect complement to the rich and creamy casserole.
For a heartier meal, consider serving it with a side of garlic bread or cheesy breadsticks. The warm, crusty bread is perfect for soaking up all that delicious sauce.
