Ingredients

• 1 lb sirloin steak, thinly sliced against the grain
• 1 tablespoon olive oil
• 2 tablespoons unsalted butter, divided
• 1 small yellow onion, finely chopped
• 8 oz cremini or button mushrooms, sliced
• 3 garlic cloves, minced
• 1 teaspoon fine salt, divided, plus more to taste
• ½ teaspoon freshly ground black pepper
• 1 tablespoon Dijon mustard
• 1 tablespoon Worcestershire sauce
• 2½ cups beef broth
• 8 oz wide egg noodles
• ¾ cup full-fat sour cream
• 2 tablespoons chopped fresh parsley, optional

Method

1. Prepare the beef. Pat the sirloin dry with paper towels. Slice it thinly against the grain and season with ½ teaspoon of the salt and the black pepper.
2. Sear the sirloin. Heat the olive oil and 1 tablespoon of butter in a large deep skillet over medium-high heat. Add the beef in a single layer, working in batches if necessary. Sear for 1–2 minutes per side, until browned on the outside. The beef does not need to be fully cooked at this stage. Transfer it to a plate.
3. Cook the vegetables. Reduce the heat to medium and add the remaining tablespoon of butter. Add the onion and cook for 3–4 minutes, until softened. Add the mushrooms and the remaining ½ teaspoon of salt. Cook for 6–8 minutes, stirring occasionally, until the mushrooms have released their moisture and started to brown.
4. Add the aromatics. Stir in the garlic and cook for 30–60 seconds. Add the Dijon mustard and Worcestershire sauce, stirring to coat the mushrooms and onions.
5. Simmer the noodles. Pour in the beef broth and scrape the bottom of the skillet to loosen any browned pieces. Add the egg noodles and stir. Bring the liquid to a gentle boil, then reduce the heat to medium-low and cover the skillet.
6. Cook until tender. Simmer for 9–12 minutes, stirring every few minutes to prevent the noodles from sticking. Cook until the noodles are tender and most of the broth has reduced to a thick, saucy consistency. If the pan becomes dry before the noodles are cooked, add a splash of broth or water.
7. Finish the stroganoff. Remove the skillet from the heat. Place the sour cream in a small bowl and stir in several spoonfuls of the hot sauce from the skillet. This tempers the sour cream and helps it combine smoothly. Stir the sour cream mixture into the noodles and mushrooms.
8. Return the beef. Add the seared sirloin and any juices from the plate back to the skillet. Stir gently and allow the beef to warm through for 1–2 minutes. Do not boil after adding the sour cream.
9. Serve. Taste and adjust the seasoning. Sprinkle with chopped parsley, if using, and serve immediately.

One-Pot Beef Stroganoff (Creamy & Rich)

This one-pot beef stroganoff is a practical comfort-food dinner made with tender sirloin strips, savoury mushrooms, egg noodles, and a creamy sour cream sauce. Everything cooks in one deep skillet, including the noodles, so the beef broth becomes part of the sauce instead of being discarded.

The process is straightforward: sear the beef, cook the mushrooms and onions, simmer the noodles in broth, then finish the dish with sour cream and Dijon mustard. The result is rich, tangy, and filling without requiring a separate pot for the pasta.

This recipe is distinct from other one-pot meals because mushrooms, sour cream, and mustard provide the characteristic stroganoff flavour. For background on the one-pot approach and related variations, see this beef stroganoff recipe guide.

Why this recipe works

Thinly sliced sirloin cooks quickly and remains tender when it is seared briefly rather than simmered for the entire cooking time. Mushrooms add savoury depth, while onion and garlic create the aromatic base.

The egg noodles cook directly in the beef broth. As they soften, their starch helps thicken the liquid. Sour cream is added at the end, away from high heat, to create a smooth sauce and reduce the risk of curdling.

Use a large, deep skillet or Dutch oven with a lid. The noodles do not need to be completely submerged at the beginning, but they should be stirred occasionally so they cook evenly.

Category: Main course
Cuisine: American-inspired
Method: One pot

Ingredients

• 1 lb sirloin steak, thinly sliced against the grain
• 1 tablespoon olive oil
• 2 tablespoons unsalted butter, divided
• 1 small yellow onion, finely chopped
• 8 oz cremini or button mushrooms, sliced
• 3 garlic cloves, minced
• 1 teaspoon fine salt, divided, plus more to taste
• ½ teaspoon freshly ground black pepper
• 1 tablespoon Dijon mustard
• 1 tablespoon Worcestershire sauce
• 2½ cups beef broth
• 8 oz wide egg noodles
• ¾ cup full-fat sour cream
• 2 tablespoons chopped fresh parsley, optional

Method

1. Prepare the beef. Pat the sirloin dry with paper towels. Slice it thinly against the grain and season with ½ teaspoon of the salt and the black pepper.

2. Sear the sirloin. Heat the olive oil and 1 tablespoon of butter in a large deep skillet over medium-high heat. Add the beef in a single layer, working in batches if necessary. Sear for 1–2 minutes per side, until browned on the outside. The beef does not need to be fully cooked at this stage. Transfer it to a plate.

3. Cook the vegetables. Reduce the heat to medium and add the remaining tablespoon of butter. Add the onion and cook for 3–4 minutes, until softened. Add the mushrooms and the remaining ½ teaspoon of salt. Cook for 6–8 minutes, stirring occasionally, until the mushrooms have released their moisture and started to brown.

4. Add the aromatics. Stir in the garlic and cook for 30–60 seconds. Add the Dijon mustard and Worcestershire sauce, stirring to coat the mushrooms and onions.

5. Simmer the noodles. Pour in the beef broth and scrape the bottom of the skillet to loosen any browned pieces. Add the egg noodles and stir. Bring the liquid to a gentle boil, then reduce the heat to medium-low and cover the skillet.

6. Cook until tender. Simmer for 9–12 minutes, stirring every few minutes to prevent the noodles from sticking. Cook until the noodles are tender and most of the broth has reduced to a thick, saucy consistency. If the pan becomes dry before the noodles are cooked, add a splash of broth or water.

7. Finish the stroganoff. Remove the skillet from the heat. Place the sour cream in a small bowl and stir in several spoonfuls of the hot sauce from the skillet. This tempers the sour cream and helps it combine smoothly. Stir the sour cream mixture into the noodles and mushrooms.

8. Return the beef. Add the seared sirloin and any juices from the plate back to the skillet. Stir gently and allow the beef to warm through for 1–2 minutes. Do not boil after adding the sour cream.

9. Serve. Taste and adjust the seasoning. Sprinkle with chopped parsley, if using, and serve immediately.

Tips for the best one-pot beef stroganoff

• Slice the steak thinly. Cutting against the grain shortens the muscle fibres and makes the sirloin easier to chew.
• Do not overcrowd the skillet. If the beef is packed tightly into the pan, it will steam instead of sear. Cook it in two batches when necessary.
• Brown the mushrooms properly. Allow their moisture to evaporate before adding the broth. This produces a deeper savoury flavour.
• Use a strongly flavoured broth. The broth becomes the base of the sauce, so a low-salt but full-flavoured beef broth provides better control over the final seasoning.
• Stir the noodles occasionally. Frequent stirring can make them break down, but leaving them untouched may cause them to stick to the pan.
• Add sour cream off the heat. Boiling can cause sour cream to separate or become grainy. Tempering it first produces a smoother sauce.
• Serve promptly. The sauce thickens as it stands. If leftovers become too thick, loosen them with a small amount of broth when reheating.

Variations

Use a different steak

Ribeye or strip steak can replace sirloin. Trim excess fat and slice the meat thinly. More economical cuts may require longer cooking and can become chewy in this quick recipe.

Add extra mushrooms

Increase the mushrooms to 12 oz or 16 oz for a more pronounced mushroom flavour. Cremini mushrooms provide a deeper taste, while white button mushrooms have a milder profile.

Substitute Greek yogurt

Plain full-fat Greek yogurt can replace sour cream, although the sauce will be slightly less tangy. Add it off the heat using the same tempering method.

Include vegetables

Frozen peas can be stirred in during the final two minutes of noodle cooking. Baby spinach can be added after the heat is turned off and folded through until wilted.

Make it alcohol-free

This recipe contains no wine or other alcohol. Beef broth, Worcestershire sauce, Dijon mustard, and mushrooms provide sufficient depth without requiring an alcoholic ingredient.

Make it richer

For a richer sauce, replace ¼ cup of the beef broth with heavy cream. Add the cream with the remaining broth before the noodles begin cooking.

Frequently asked questions

Can I use ground beef instead of sirloin?

Yes. Brown 1 lb of ground beef in the skillet, breaking it into small pieces, then continue with the mushrooms, broth, noodles, and sour cream. Ground beef does not need to be removed before the noodles are cooked.

Can I make beef stroganoff without mushrooms?

Yes, although mushrooms are a defining ingredient in this version and contribute substantial savoury flavour. If omitting them, consider adding extra onion or a small amount of finely chopped bell pepper.

Why did my sour cream curdle?

Sour cream can curdle when exposed to high heat or boiling liquid. Remove the skillet from the heat, temper the sour cream with a few spoonfuls of the hot sauce, and stir it into the dish gradually. Do not boil the stroganoff after the sour cream has been added.

Can I prepare this recipe ahead of time?

It is best served immediately because the noodles continue to absorb the sauce. If preparing it ahead, reserve a little beef broth for reheating. Store the cooled stroganoff in an airtight container in the refrigerator for up to 3 days.

What can I serve with one-pot beef stroganoff?

The dish is complete with beef, mushrooms, noodles, and sauce. A simple green salad, steamed green beans, or roasted broccoli can be served alongside it.
