Ingredient Guide
Choosing the right ingredients when making this Keto Beef Stroganoff Casserole Recipe really sets you up for success. Freshness and quality matter here — they’re the key to that deep, savory flavor and creamy texture that make this dish so comforting.
- Ground Beef: I like to use 80/20 ground beef for a nice balance of flavor and fat. It keeps the casserole moist and juicy without needing extra oil.
- Onion: A medium yellow or white onion diced finely gives sweetness and depth—don’t skip or swap with too mild an option.
- Mushrooms: Fresh button or cremini mushrooms sliced thinly add that classic earthy bite stroganoff is known for.
- Garlic: Freshly minced garlic adds warmth and a little punch. It pairs perfectly with the sour cream’s creaminess.
- Beef Broth: Use a good-quality low-sodium beef broth to control salt and add an umami kick.
- Sour Cream: Full-fat sour cream is a must for that luscious, creamy sauce that hugs every bite.
- Cheddar Cheese: Sharp cheddar melts well and gives the casserole a rich, golden top. Feel free to experiment with mild or medium if that’s what you have.
- Worcestershire Sauce (optional): Just a splash enhances the meaty flavor without being overpowering.
- Seasoning: Salt, pepper, and a teaspoon of Italian seasoning round things out beautifully.

How to Make Keto Beef Stroganoff Casserole Recipe
Step 1 — Prep & Ready
Start by preheating your oven to 350°F (175°C). While the oven warms, dice your onion, slice your mushrooms, and mince the garlic. This simple prep sets you up for a smooth cooking process. When handling your ground beef, I find it easiest to have it at slightly chilled temperature for easy break-up and even browning. Season it lightly with salt and pepper before cooking — just a little extra step to develop more flavor in the beef.
Step 2 — Cook with Confidence
Heat a large skillet over medium heat, then add your ground beef. As it browns, break it apart with your spatula or spoon. You’ll notice the aroma shift to a rich, meaty scent that’s so satisfying. Drain any excess fat so your casserole doesn’t get greasy. Next, toss in the diced onion, garlic, and sliced mushrooms. Cook everything until the onions soften and mushrooms reduce, about 5-7 minutes — you’ll see the mushrooms release their earthy juice, and the colors brighten beautifully. Stir in the beef broth, sour cream, Worcestershire sauce if you’re using it, Italian seasoning, and adjust salt and pepper to taste. The sauce should be creamy and slightly thick but still pourable.
Step 3 — Finish & Serve
Transfer the creamy beef and mushroom mixture to your baking dish and sprinkle a generous layer of shredded cheddar over the top. Pop it in the oven for 25-30 minutes or until the cheese bubbles and turns a gorgeous golden brown. When you pull it out, you’ll love the cozy aroma and see that crispy cheese edge forming around the casserole. Let it rest just a few minutes before serving — this helps everything set nicely for easy scooping. Serve it on its own or with your favorite keto sides for a satisfying meal.
Extra Helpful Tips
I want you to enjoy making this Keto Beef Stroganoff Casserole Recipe as much as eating it, so here are some tips from my kitchen to yours that helped me feel confident and get great results every time.
- Watch for This Sign: When browning beef, make sure it’s nicely caramelized but not burnt; this layer adds incredible depth to your casserole.
- Temperature Trick: Don’t add the sour cream directly to high heat; stirring it in off the burner or at low heat avoids curdling and keeps the sauce silky.
- Prep-Ahead Option: You can prepare the beef and mushroom mixture a day ahead, cover tightly, and bake the next day with just the cheese added before popping it in the oven.
- Avoid This Common Mistake: Resist the urge to skip draining fat—too much grease can make the casserole oily and weigh down the flavors.
Serve & Enjoy
Easy Enhancements
Want to put a twist on your Keto Beef Stroganoff Casserole Recipe? Try stirring fresh chopped parsley or chives over the top just before serving for a pop of color and freshness. A splash of smoked paprika or a pinch of cayenne can add a subtle warmth if you like a bit of spice. For extra richness, crumble some cooked bacon into the mix or sprinkle crispy fried shallots as a topping after baking.
Tasty Pairings
This casserole stands beautifully on its own, but when you want to round out the meal, think steamed broccoli or garlicky sautéed green beans on the side to add fresh, bright contrast. A simple keto-friendly salad with tangy vinaigrette cuts through the richness perfectly. For drinks, a dry red wine or sparkling water with lemon complements the savory notes without overwhelming your palate.
Quick Plating Tips
For a simple, pretty presentation, scoop the casserole onto plates and garnish with a sprinkle of fresh herbs like parsley. Drizzle a little extra sour cream or a dollop of crème fraîche on top for a creamy finish. If you’re serving guests, fresh cracked black pepper and a tiny pinch of smoked paprika on the cheese crust can make it look extra inviting in minutes.
Store, Freeze & Reheat
Fridge Storage
Store leftover Keto Beef Stroganoff Casserole Recipe in an airtight container in the fridge for up to 3-4 days. The flavors actually deepen after resting, but the texture will firm up slightly, so warming gently is key to enjoying it at its best.
Freezer Friendly?
This casserole freezes well if you want to make it in advance. Freeze in a well-sealed container for up to 3 months. When ready to eat, thaw overnight in the fridge to reduce excess moisture and prevent it from becoming soggy when reheated.
Reheat Like New
Reheat gently in the oven at 325°F, covered loosely with foil, until warmed through (about 15-20 minutes). You can also microwave in short bursts, stirring in between, to keep it creamy without drying. A splash of beef broth or sour cream when reheating helps maintain that creamy texture that makes this Keto Beef Stroganoff Casserole Recipe so satisfying.
Keto Beef Stroganoff Casserole Recipe FAQs
Yes! Ground turkey or chicken works if you prefer poultry, but keep in mind that it’s leaner, so you might want to add a little extra fat like butter or olive oil during cooking to keep the casserole moist and flavorful.
Absolutely. This recipe is designed to be low-carb, focusing on high-fat ingredients like sour cream and cheese while keeping carbs from starches minimal. Just be sure to use full-fat dairy and check your seasonings for hidden sugars.
You can try substituting sour cream with a dairy-free alternative like coconut cream and use dairy-free cheese, but the flavor and texture will change. It's worth experimenting, but I’d recommend trying it as written first to enjoy the creamy classic taste.
The sauce should be thick enough to coat the back of a spoon but still pourable. If it’s too runny, it might result in a watery casserole. Cook it a few extra minutes on the stove if needed to reduce and thicken before transferring to the baking dish.
Final Flavor Thoughts
This Keto Beef Stroganoff Casserole Recipe has become one of my absolute favorites when I want comfort food that fits my low-carb lifestyle. I hope it feels as cozy and satisfying in your kitchen as it does in mine. If you give it a try, let me know what you think — maybe leave a star rating or drop a comment with your favorite tweak.
