Instructions

1. Prep your ingredients. Slice the mushrooms, chop the onion, and mince the garlic.

   Have your spices and liquids measured and ready. This recipe moves fast once the pan is hot.

2. Brown the mushrooms. Heat a large skillet over medium-high heat. Add 1 tablespoon butter and the olive oil.

   Add the mushrooms in a single layer and let them sear undisturbed for 2–3 minutes. Stir and cook another 3–4 minutes until browned and reduced. Season with a pinch of salt, then transfer to a plate.

3. Cook the beef. In the same skillet, add the ground beef.

   Break it up and cook until browned with crispy edges, about 6–8 minutes. Season with salt, pepper, and smoked paprika. If there’s excessive grease, spoon off a bit, but leave some for flavor.

4. Soften the aromatics. Push the beef to one side.

   Add the remaining 1 tablespoon butter to the empty space, then add the onion. Cook 2–3 minutes until translucent. Stir in the garlic and thyme for 30 seconds until fragrant.

5. Deglaze and build the sauce. Pour in the beef broth, scraping up any browned bits from the pan.

   Stir in Worcestershire and Dijon. Let it simmer for 2 minutes to reduce slightly.

6. Bring it together. Return the mushrooms to the pan and toss with the beef. Reduce the heat to medium-low and stir in the heavy cream.

   Simmer gently for 2–3 minutes until the sauce thickens and coats the mixture. If using Parmesan, sprinkle it in and stir until melted and silky. Adjust salt and pepper, and add red pepper flakes if you like a kick.

7. Serve. Sprinkle with chopped parsley.

   Spoon over cauliflower rice, zucchini noodles, or steamed green beans. For extra richness, finish with a small pat of butter on top.

How to Store

Let the skillet cool, then transfer to an airtight container. It keeps well in the fridge for 3–4 days.

Reheat gently on the stovetop over low heat or in the microwave at 50–70% power so the sauce doesn’t split. If it thickens too much in the fridge, loosen with a splash of broth or a bit of cream while warming.

Benefits of This Recipe

• Low in carbs, high in satisfaction: You get the comfort of a creamy, savory skillet without the starches.
• Protein-forward: Ground beef offers staying power and helps support a balanced, low-carb lifestyle.
• One-pan convenience: Minimal cleanup and no complicated techniques.
• Flexible ingredients: Works with any mushroom variety and adapts to dairy-free or different proteins.
• Meal-prep friendly: Holds up well in the fridge and reheats smoothly.

Pitfalls to Watch Out For

• Overcrowding the pan: Mushrooms steam instead of brown if the pan is packed. Cook in batches if needed.
• Skipping the deglaze: Those browned bits equal flavor.

  Use broth to lift them into the sauce.

• Too much grease: If your beef is very fatty, spoon off some fat before adding liquids or the sauce can feel heavy.
• Boiling the cream: Keep the heat moderate so the sauce stays smooth and doesn’t break.
• Under-seasoning: Taste as you go. Mushrooms and cream both need enough salt and pepper to shine.

Variations You Can Try

• Turkey or chicken version: Swap in ground turkey or chicken. Add an extra splash of broth and a bit more salt, since poultry is milder.
• Dairy-free: Use olive oil or ghee, coconut cream instead of heavy cream, and skip the Parmesan.

  A squeeze of lemon at the end brightens the flavor.

• Swiss-inspired: Add a handful of shredded Swiss or Gruyère instead of Parmesan and toss in a splash of dry white wine when deglazing.
• Herb swap: Try rosemary or Italian seasoning if you don’t have thyme. Fresh chives at the end are great too.
• Umami boost: Add 1/2 teaspoon soy sauce or tamari with the Worcestershire. If you’re strict low-carb, check labels.
• More veg: Stir in a handful of baby spinach or chopped kale in the last minute of cooking until wilted.
• Spice lovers: Use hot smoked paprika, add extra red pepper flakes, or a dash of chili crisp on top.

FAQ

Can I use lean ground beef?

Yes.

Lean beef works, but you may want to add a little extra butter or oil for flavor and a richer mouthfeel. Keep an eye on seasoning, since fat carries flavor.

What mushrooms are best?

Cremini or baby bellas have great flavor and hold up well. White button mushrooms also work.

If you want a meatier bite, mix in some sliced portobellos.

Is this recipe keto-friendly?

It can be. Use heavy cream and a low-carb Worcestershire or tamari, and serve over cauliflower rice or zucchini noodles. Always check labels to confirm net carbs.

Can I make it ahead?

Absolutely.

Cook as directed, cool, and refrigerate. Reheat gently and add a splash of broth if needed to loosen the sauce.

What can I serve it with besides cauliflower rice?

Try sautéed cabbage, roasted asparagus, garlicky spinach, or a simple green salad with a tangy vinaigrette. It’s also great over mashed cauliflower.

How can I thicken the sauce without flour?

Let it simmer a bit longer to reduce, or add a small handful of Parmesan to tighten the sauce naturally.

A knob of cream cheese also works in a pinch.

Can I freeze it?

You can, but cream sauces can separate after freezing. If you plan to freeze, skip the cream and cheese, freeze the beef-mushroom base, then add the dairy when reheating.

What if I don’t have beef broth?

Use chicken or vegetable broth. Even water works in a pinch with a bit more salt and a dash of soy or Worcestershire for depth.

How do I keep zucchini noodles from getting watery?

Salt them lightly and let them sit for 10 minutes, then pat dry.

Sauté quickly over high heat just before serving, and top with the skillet instead of mixing everything together in the pan.

Can I add cheese on top?

Yes, a sprinkle of shredded mozzarella or Gruyère melted under the broiler for a minute makes it extra cozy. Just keep an eye on the broiler so it doesn’t burn.
