Ingredients

  

• For the steaks: 1 1/2 pounds (680 g) ground beef, 80–85% lean
• 1/3 cup finely minced onion
• 1 large egg
• 1/3 cup almond flour (or crushed pork rinds)
• 1 tablespoon Worcestershire sauce (check for low sugar)
• 1 teaspoon Dijon mustard
• 1 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1 teaspoon kosher salt
• 1/2 teaspoon black pepper
• 2 tablespoons butter or avocado oil for searing
• For the mushroom gravy: 2 tablespoons butter
• 8 ounces (225 g) cremini or white mushrooms, sliced
• 1 small onion, thinly sliced
• 2 cloves garlic, minced
• 1 1/2 cups beef broth (low sodium)
• 1 tablespoon Worcestershire sauce
• 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried)
• 1/2 teaspoon smoked paprika (optional)
• 1/4 cup heavy cream (optional, for richer gravy)
• 1/2 teaspoon xanthan gum (use 1/4 teaspoon at a time), or reduce to thicken naturally
• Salt and pepper to taste
• To serve: Chopped fresh parsley
• Cauliflower mash, zucchini noodles, or steamed greens

Method

 

1. Mix the steaks. In a large bowl, combine ground beef, minced onion, egg, almond flour, Worcestershire, Dijon, garlic powder, onion powder, salt, and pepper. Mix gently with your hands until just combined. Don’t overwork the meat.
2. Shape the patties. Form 5–6 oval patties, about 3/4-inch thick. Press a shallow dimple in the center of each to prevent doming.
3. Sear the steaks. Heat butter or oil in a large skillet over medium-high. Sear patties 3–4 minutes per side until browned. Transfer to a plate; they’ll finish cooking in the gravy.
4. Sauté onions and mushrooms. Lower heat to medium. Add 2 tablespoons butter, then sliced onions and mushrooms. Cook 6–8 minutes, stirring, until they release liquid and start to brown.
5. Add garlic and season. Stir in garlic, thyme, and smoked paprika. Cook 30–60 seconds until fragrant.
6. Build the gravy. Pour in beef broth and Worcestershire, scraping up browned bits. Simmer 3–4 minutes to reduce slightly.
7. Thicken. If using xanthan gum, sprinkle in 1/4 teaspoon while whisking constantly. Let it simmer 1–2 minutes, then add more if needed. Alternatively, simmer longer to reduce naturally. Stir in heavy cream if using. Taste and season with salt and pepper.
8. Finish the steaks. Nestle patties into the gravy along with any juices. Cover and simmer 6–8 minutes, flipping once, until cooked through (internal temp about 160°F/71°C).
9. Serve. Spoon gravy over the steaks, garnish with parsley, and serve with cauliflower mash or your favorite low-carb side.

Keeping It Fresh

• Refrigerate: Store in an airtight container with gravy for up to 4 days. The gravy helps keep the steaks moist.
• Freeze: Cool completely. Freeze steaks covered in gravy in a freezer-safe container for up to 2 months.

  Thaw overnight in the fridge.

• Reheat: Warm gently on the stovetop over low heat, adding a splash of broth or cream if the gravy is too thick.

Benefits of This Recipe

• Keto-friendly and satisfying. High in protein and fat with minimal carbs, it keeps you full and supports ketosis.
• Balanced flavors. Umami-rich mushrooms, savory beef, and a silky gravy deliver that classic comfort feel without flour or sugar.
• Customizable macros. Adjust cream, butter, or lean-to-fat ratio in the beef to fit your goals.
• Great for meal prep. Holds up well in the fridge and tastes even better the next day.

Common Mistakes to Avoid

• Overmixing the meat. This makes the patties tough. Mix until just combined.
• Skipping the sear. Browning adds flavor and helps the patties hold together in the gravy.
• Dumping in too much xanthan. Start small. A little goes a long way and can turn gummy if overused.
• Not reducing the gravy. Let it simmer to concentrate flavor before thickening.
• Using very lean beef without fat adjustments. If your beef is lean, add a tablespoon of butter to the pan or an extra splash of cream to the gravy.

Recipe Variations

• French onion twist: Caramelize the onions longer and add a splash of dry white wine (or more broth) before simmering.
• Creamier gravy: Increase heavy cream to 1/2 cup and finish with a knob of butter for a silky finish.
• Pork and beef blend: Use half ground pork for extra tenderness and flavor.
• Herb-forward: Swap thyme for rosemary or Italian seasoning.

  Fresh parsley stems can simmer in the gravy for extra aroma.

• Dairy-free: Use ghee or olive oil for searing, skip the cream, and thicken with a small amount of xanthan or by reduction.
• Mushroom medley: Mix cremini with shiitake or portobello for deeper umami.

FAQ

Is Worcestershire sauce keto?

Most brands contain small amounts of sugar, but the quantity used here is low and typically fits within daily carb limits. If you’re strict, look for a sugar-free version or reduce the amount and boost umami with a bit of tamari or coconut aminos.

Can I make this without xanthan gum?

Yes. Simply simmer the gravy longer to reduce and thicken naturally.

You can also blend a few cooked mushrooms and onions into the broth to add body.

What’s the best side dish for keto Salisbury steak?

Cauliflower mash is the classic pairing. You can also serve it over sautéed cabbage, roasted asparagus, zucchini noodles, or a buttery cauliflower rice pilaf.

How do I keep the patties from falling apart?

Use the egg and almond flour for structure, and make sure to sear well on both sides before adding to the gravy. Avoid flipping too often, and let a good crust form.

Can I use ground turkey or chicken?

You can, but the flavor and texture will be lighter.

Add extra fat (a tablespoon of butter or olive oil) and bump up the seasonings to keep it juicy and flavorful.

How can I make the gravy extra rich?

Finish with heavy cream and a tablespoon of butter, and simmer until glossy. A splash of coffee or a few drops of fish sauce can also deepen the savory notes without tasting fishy.
