Tips for Making Baked Ground Beef Stroganoff Casserole

Give the mushrooms enough space in the skillet for their moisture to evaporate. Cooking a crowded pan of mushrooms can leave extra liquid that thins the sauce.

Avoid overcooking the noodles during any precooking step, since they continue softening in the oven. Follow the preparation method in the recipe rather than adding dry noodles directly.

Lower the heat before incorporating sour cream, and avoid boiling the sauce vigorously afterward. Coat the noodles evenly with sauce before transferring everything to the baking dish so exposed pieces are less likely to dry out.

Ingredients Equipment Method Notes

Ingredients

  

• 1 lb lean ground beef 90/10
• 12 oz wide egg noodles uncooked
• 1 tbsp olive oil
• 1 medium yellow onion finely diced
• 8 oz cremini mushrooms sliced
• 3 cloves garlic minced
• 2 tbsp all-purpose flour
• 2 cups low-sodium beef broth
• 1 tbsp Worcestershire sauce
• 1 tsp Dijon mustard
• 1/2 tsp smoked paprika
• 1/2 tsp kosher salt or to taste
• 1/4 tsp freshly ground black pepper
• 3/4 cup sour cream
• 1 cup shredded mozzarella cheese
• 1/2 cup shredded sharp cheddar cheese
• 2 tbsp chopped fresh parsley for garnish

Equipment

• 1 9×13-inch baking dish
• 1 Large skillet
• 1 Large pot
• 1 Colander
• 1 Mixing spoon
• 1 Measuring cups and spoons

Method

 

1. Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
2. Bring a large pot of salted water to a boil. Cook the egg noodles for about 2 minutes less than the package directions. Drain and set aside.
3. Heat the olive oil in a large skillet over medium-high heat. Add the ground beef and cook for 5–7 minutes, breaking it apart until browned and fully cooked. Drain excess grease if necessary.
4. Add the diced onion and sliced mushrooms. Cook for 5 minutes, stirring occasionally, until the vegetables begin to soften.
5. Stir in the minced garlic and cook for 30 seconds until fragrant.
6. Sprinkle the flour over the beef mixture and stir for 1 minute.
7. Gradually pour in the beef broth while stirring. Add the Worcestershire sauce, Dijon mustard, smoked paprika, salt, and black pepper. Simmer for 3–5 minutes until the sauce thickens.
8. Reduce the heat to low. Remove the skillet from the heat and stir in the sour cream until the sauce is smooth and creamy.
9. Add the cooked egg noodles to the skillet and gently toss until evenly coated with the creamy beef mixture.
10. Transfer the mixture to the prepared baking dish. Sprinkle the mozzarella and cheddar cheese evenly over the top.
11. Bake uncovered for 12–15 minutes, or until the casserole is bubbling and the cheese is melted. The center should reach 165°F (74°C).
12. Remove from the oven and let rest for 5 minutes. Garnish with fresh parsley and serve warm.

Notes

Recipe Tips

• Use lean ground beef to reduce excess grease.
• Cook the egg noodles slightly under the package directions because they will continue cooking in the oven.
• Use cremini mushrooms for a rich, savory flavor.
• Add the sour cream after removing the skillet from the heat to keep the sauce creamy.
• For extra flavor, use freshly shredded cheddar cheese.

Make Ahead: Assemble the casserole up to 24 hours in advance. Cover and refrigerate until ready to bake. Add extra baking time if needed.

Storage: Refrigerate leftovers in an airtight container for 3–4 days.

Freezing: Freeze cooled portions in freezer-safe containers for up to 2 months for best quality.

Reheating: Reheat in the oven at 350°F until heated throughout. Add a splash of beef broth if the noodles seem dry.

Safe Cooking Temperatures

Cook ground beef to an internal temperature of 160°F (71°C). When baking the assembled casserole, check that its center reaches 165°F (74°C). A browned cheese topping does not confirm that the middle is hot enough.

Use a food thermometer and consult the FoodSafety.gov safe cooking temperature chart for detailed guidance.

How to Store and Reheat Stroganoff Casserole

Divide leftovers into shallow containers and refrigerate promptly at 40°F or below. Use refrigerated leftovers within three to four days.

Do not leave the casserole unrefrigerated for more than two hours, or one hour when temperatures exceed 90°F.

Reheat individual portions covered, adding a small splash of broth if the noodles have absorbed much of the sauce. Check that the food reaches 165°F throughout. When using a microwave, check several spots because the center and edges may heat unevenly.

Frequently Asked Questions

Why is my casserole dry?

Noodles absorb sauce as they cook and stand. Overbaking or using more noodles than the recipe specifies can leave the casserole dry. Measure the noodles carefully and check the dish before adding extra oven time.

Why did my sour cream sauce become grainy?

High heat can cause sour cream to separate. Reduce the heat before adding it and stir gently. Avoid a vigorous boil once the sour cream is incorporated.

Can I use a different pasta shape?

Short pasta can offer a different texture, but cooking times and sauce absorption vary. Keep the same dry weight as a starting point and check the pasta during precooking rather than assuming identical timing.

What should I serve with it?

Steamed green beans, roasted broccoli, or a cucumber salad provides contrast to the creamy filling. A simple vegetable side keeps the meal easy to organize.
