Ingredients

• 12 oz wide egg noodles, uncooked
• 1 lb beef sirloin or flank steak, thinly sliced
• 8 oz sliced white button or cremini mushrooms
• 2 cans (10.5 oz each) condensed cream of mushroom soup
• 2 cups sour cream
• 1 1/2 cups water
• 1 1/2 tsp kosher salt, divided
• 1 tsp black pepper, divided
• 1 tbsp neutral oil, for searing
• Nonstick cooking spray

How to Make Oven-Baked Beef Stroganoff Pasta

1. Prepare the oven and casserole dish

Preheat the oven to 350°F (175°C). Lightly coat a 9×13-inch casserole dish with nonstick cooking spray.

2. Season and sear the beef

Cut the beef into thin strips against the grain. Pat it dry and season with about 1/2 teaspoon salt and 1/2 teaspoon black pepper.

Heat the oil in a large skillet over medium-high heat. Sear the beef for about 1–2 minutes per side, working in batches if necessary. The beef does not need to be completely cooked at this stage because it will finish cooking in the oven.

Transfer the browned beef to a plate.

3. Make the creamy stroganoff sauce

In a large bowl, whisk together the cream of mushroom soup, sour cream, water, remaining salt, and remaining black pepper until smooth.

This creates the rich, creamy sauce that coats the noodles as they bake.

4. Add the noodles and mushrooms

Add the uncooked egg noodles and sliced mushrooms to the sauce. Toss gently until the noodles are thoroughly coated and the mushrooms are evenly distributed.

5. Layer the casserole

Spread half of the noodle mixture into the prepared baking dish. Add half of the browned beef.

Repeat with the remaining noodles and beef. Press everything down gently so the ingredients are nestled into the sauce.

Make sure most of the noodles are covered with sauce so they cook evenly.

6. Bake covered

Cover the casserole tightly with aluminum foil and bake for 30 minutes.

The covered baking time allows the noodles to soften while the beef finishes cooking in the creamy sauce.

7. Finish baking uncovered

Carefully remove the foil because hot steam will escape. Gently stir from the edges toward the center, bringing some sauce over any exposed noodles.

Return the casserole to the oven uncovered and bake for another 10–15 minutes, or until the noodles are tender, the beef is cooked through, and the sauce is bubbling.

8. Rest and serve

Let the casserole rest for 5–10 minutes before serving. This gives the sauce time to thicken and cling to the noodles.

Serve generous portions of creamy noodles, tender beef, and mushrooms straight from the casserole dish.

What to Serve With Beef Stroganoff Pasta

Because this casserole is hearty and creamy, it pairs especially well with fresh or lightly cooked vegetables.

Try serving it with:

• Green salad with a tangy vinaigrette
• Steamed green beans with lemon
• Roasted carrots
• Simple fruit salad
• Warm dinner rolls
• Buttered toast

Easy Recipe Variations

Use ground beef

For a more budget-friendly ground beef stroganoff casserole, replace the steak with 1 lb ground beef. Brown it thoroughly, drain excess fat, and use it in place of the beef strips.

Add Dijon and Worcestershire

For a deeper, more traditional stroganoff flavor, add about 1 teaspoon Dijon mustard and a splash of Worcestershire sauce to the creamy sauce.

Use Greek yogurt

Replace up to half of the sour cream with plain Greek yogurt for a slightly tangier flavor.

Make it mushroom-free

If your family isn’t a fan of mushrooms, leave them out and add frozen peas or green beans during the final 10 minutes of baking.

Make-Ahead Instructions

You can assemble the casserole up to 24 hours in advance. Cover it tightly and refrigerate until you’re ready to bake.

Because the casserole will be cold from the refrigerator, allow approximately 5–10 additional minutes during the covered baking stage. Check that the noodles are tender and the beef is fully cooked before serving.

How to Store Leftovers

Allow leftovers to cool promptly and transfer them to an airtight container. Refrigerate for 3–4 days.

When reheating, add a small splash of water or milk to loosen the creamy sauce. Reheat until the center reaches 165°F.

Recipe Tips

• Slice the beef thinly and cut against the grain for more tender pieces.
• Don’t fully cook the beef during the initial searing step.
• Keep the casserole tightly covered during the first part of baking.
• Make sure the uncooked noodles are well coated with sauce.
• Let the casserole rest before serving so the sauce can thicken.
• If the noodles appear dry after removing the foil, gently stir them into the sauce before finishing the bake.

Frequently Asked Questions

Can I use ground beef instead of steak?

Yes. Ground beef is an excellent substitute and makes this casserole more economical. Brown 1 lb of ground beef, drain it, and layer it into the casserole as directed.

Can I make beef stroganoff pasta ahead of time?

Yes. Assemble the casserole, cover it tightly, and refrigerate it for up to 24 hours before baking.

Can I use a different type of pasta?

Wide egg noodles work especially well because they cook into the creamy sauce and have the classic stroganoff texture. Other pasta shapes may require adjustments to the liquid and cooking time.

How long does beef stroganoff pasta last in the refrigerator?

Store leftovers in an airtight container in the refrigerator for 3–4 days. Reheat thoroughly before serving.
