Why This Crock Pot Steak Stroganoff Works
The stroganoff sauce gets this deep, earthy flavor from the mushrooms.
I’ve made this on busy Sundays when Noah has back-to-back baseball games and we need something ready when we get home.

Bennett refused to eat it (shocker), but Chloe asked for seconds, which almost never happens
What Makes Crock Pot Steak Stroganoff Rich
This stroganoff gets its flavor from cremini mushrooms slow-cooked with garlic and onion until everything melts together. The sour cream goes in at the end so it stays silky.
✔ Cremini mushrooms: meatier than button mushrooms, hold up better in the slow cooker
✔ Sour cream: makes the sauce creamy and tangy, add it at the end so it doesn’t separate
✔ Egg noodles: classic stroganoff base, wide and perfect for catching sauce
✔ Dijon mustard: hidden ingredient that makes people ask “what’s in this?”
The whole thing comes together faster than you’d think, especially if you prep the night before.
How to Make Crock Pot Steak Stroganoff (The Real Way)
Steak stroganoff in the Crock Pot basically involves layering everything, letting it cook low and slow, stirring in sour cream at the end. The paprika and Dijon mustard do most of the heavy lifting flavor-wise.
Brown the Aromatics
Heat olive oil in a skillet, sauté diced onion and minced garlic until fragrant.
Add the Mushrooms
Toss in sliced cremini mushrooms and cook until they release their liquid.
Transfer to Crock Pot
Move everything to your slow cooker, add beef broth and Worcestershire sauce.
Season and Cook
Stir in paprika, salt, pepper, cover and cook on LOW for 6 hours.
Finish with Cream
About 20 minutes before serving, whisk cornstarch with a little broth, stir it in, add sour cream.
Cook the Noodles
Boil egg noodles separately according to package directions, drain and serve stroganoff over top.
Now if you want to switch things up, there are some solid variations. Or try slow cooker beef and noodles next.
Ways to Customize Your Crock Pot Steak Stroganoff
Steak Stroganoff with Cube Steak Slow Cooker
Use cube steak instead of regular beef strips. It gets ridiculously tender after 6 hours and soaks up the stroganoff sauce like a sponge. I tried this when cube steak was on sale at King Soopers, and Rachel actually preferred it. Just cut the steaks into strips before adding them.
Can I Thicken Stroganoff Without Flour?
Yeah, use cornstarch slurry like I do in the recipe, or skip it entirely and let the sauce reduce naturally on HIGH for the last 30 minutes with the lid off. The sour cream thickens it anyway. I’ve also used arrowroot powder when Rachel was on a gluten-free kick, worked fine.
Swap Greek Yogurt for Sour Cream in Stroganoff
Full-fat Greek yogurt works if you’re out of sour cream. Just temper it first by mixing with some hot broth before stirring it in, otherwise it’ll curdle. The flavor’s a little less tangy but still creamy. Chloe couldn’t tell the difference, which says a lot.
Once it’s ready, you’ll want something to go with it.
What to Serve with Crock Pot Steak Stroganoff
Honestly, egg noodles are the classic move and for good reason. They soak up the stroganoff sauce perfectly and make the whole thing feel like a proper meal. At home, I usually just dump the stroganoff right over a big bowl of buttered noodles and call it dinner.
Mashed potatoes work surprisingly well if you’re not feeling noodles. The creamy-on-creamy thing sounds weird but it’s actually comforting, especially on cold Denver nights. Noah requests this combo during Broncos games. Think crock pot brown gravy vibes.
Steak stroganoff over rice is a thing too, and honestly it stretches the meal further when we have unexpected guests (which happens more than I’d like). White or brown rice, doesn’t matter, both catch the sauce nicely.
Roasted green beans add some color and crunch, which the kids appreciate. I toss them with olive oil and garlic, roast at 425°F for 15 minutes while the stroganoff finishes up. Easy side that doesn’t require thinking.
If you’ve got leftovers (rare in this house), here’s how to keep them good.
Keeping Your Crock Pot Steak Stroganoff Fresh
This steak stroganoff keeps really well, which is why I make a double batch sometimes. The creamy sauce reheats better than you’d think.
Storage
- At room temperature: Only safe for about 2 hours, especially with the sour cream base
- In the fridge: Transfer to an airtight container, good for 3-4 days easy
- In the freezer: Freeze the base without sour cream, add fresh cream when reheating (lasts 2-3 months)
Reheating
Stovetop on medium-low is best, add a splash of beef broth to loosen it up. Microwave works in a pinch, just cover and heat in 90-second bursts, stirring between. Crock Pot on LOW for an hour brings it back to life perfectly.
Anti-waste Tip
Use leftover stroganoff as a filling for stuffed bell peppers. Mix it with cooked rice, stuff the peppers, bake at 375°F for 30 minutes. Totally different meal.

Questions About Crock Pot Steak Stroganoff
When I first made steak stroganoff in the slow cooker, I wasn’t sure if the sour cream would curdle. Turns out, timing matters.
Can you make mushroom stroganoff in Crock Pot for kids?
Absolutely. Use extra beef broth, go easy on the pepper, and serve it over noodles my kids eat it without a single complaint.
Why did my stroganoff turn out watery?
Happened to me too. Either skip deglazing or use the cornstarch slurry to thicken it at the end. HIGH uncovered for 20 minutes helps too.
When do you add sour cream to slow cooker stroganoff?
Always at the end, last 20 minutes. If you add it too early, it separates and gets grainy. Trust me on this.
Can I use steak stroganoff over rice instead of noodles?
Yeah, works great. White or brown rice both catch the sauce nicely. I do this when I’m meal prepping for the week.

Crock Pot Steak Stroganoff
Equipment
- 6-quart Crock Pot

- Whisk
Ingredients
- 1 tablespoon olive oil
- 0.5 diced onion
- 8 ounces sliced cremini mushrooms
- 2 teaspoons minced garlic
- 3 cups beef broth
- 1 tablespoon Worcestershire sauce
- 1 teaspoon paprika
- 2 tablespoons cornstarch
- 1 cup sour cream
- 1 teaspoon salt
- 1 teaspoon pepper
- 12 ounces egg noodles
Instructions
- Heat olive oil in a large skillet over medium heat.
- Add diced onion and minced garlic, sauté for 3-4 minutes until fragrant.
- Add sliced cremini mushrooms and cook until they release their liquid, about 5 minutes.
- Transfer everything to your Crock Pot, add beef broth, Worcestershire sauce, paprika, salt, and pepper.
- Cover and cook on LOW for 6 hours.
- About 20 minutes before serving, whisk cornstarch with 2 tablespoons of the hot liquid, stir it back into the Crock Pot.

- Meanwhile, cook egg noodles according to package directions and drain.
- Serve stroganoff over hot egg noodles, garnish with fresh parsley if you have it.
Notes
- If you’re using cube steak, cut it into strips before adding it to the Crock Pot in step 5. It’ll break down beautifully and get super tender.
- Rachel prefers Greek yogurt to sour cream, so I temper it first with hot broth to prevent curdling.
- One time I added the sour cream too early and it separated into this weird grainy mess, so definitely wait until the last 20 minutes.
