Ingredients Method

Ingredients

  

• 2 pounds beef sirloin, flank, or chuck roast, thinly sliced against the grain
• 2 tablespoons butter or avocado oil
• 1 large yellow onion, thinly sliced
• 1 green bell pepper, thinly sliced
• 1 red bell pepper, thinly sliced (optional for sweetness and color)
• 8 ounces mushrooms, sliced (white or cremini)
• 4 cloves garlic, minced
• 4 cups beef broth, low-sodium
• 1 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper
• 1 teaspoon onion powder
• 1 teaspoon dried Italian seasoning or oregano
• 1 tablespoon Worcestershire sauce (check labels; optional but tasty)
• 4 ounces cream cheese, softened and cubed
• 6-8 slices provolone cheese, torn into pieces (or 1 1/2 cups shredded provolone)
• 1/2 cup heavy cream
• Fresh parsley, chopped, for garnish (optional)

Method

 

1. Slice the beef thin: For easier slicing, chill the beef in the freezer for 20–30 minutes. Slice against the grain into thin strips. This keeps it tender.
2. Sauté the aromatics (optional but recommended): In a skillet over medium heat, melt butter. Add onions and peppers and cook 5–7 minutes until softened and lightly browned. Add mushrooms and cook 3 minutes more. Stir in garlic for 30 seconds. Transfer everything to the crockpot.
3. Layer the beef: Add sliced beef on top of the veggies in the crockpot.
4. Add seasonings and broth: Sprinkle in salt, pepper, onion powder, and Italian seasoning. Pour in beef broth and Worcestershire. Stir gently to combine.
5. Slow cook: Cover and cook on Low for 6–7 hours or on High for 3–4 hours, until the beef is very tender.
6. Stir in the creamy elements: Switch to Low (or keep on Low if already there). Add cream cheese cubes and heavy cream. Stir until the cream cheese melts and the broth turns creamy, about 10–15 minutes.
7. Add the provolone: Stir in provolone in batches until melted and smooth. Taste and adjust salt and pepper.
8. Serve: Ladle into bowls and garnish with chopped parsley. For extra cheesesteak vibes, top with an additional slice of provolone and let it melt on top.

Storage Instructions

• Fridge: Cool completely, then store in airtight containers for up to 4 days.

  The soup will thicken slightly as it chills.

• Reheat: Warm gently on the stove over low heat, stirring often. If it’s too thick, add a splash of broth or cream. Avoid boiling to prevent cheese separation.
• Freezer: Dairy-based soups can separate when frozen.

  If you want to freeze, do so before adding cream and cheeses. Add them fresh when reheating.

Benefits of This Recipe

• Low in carbs, high in satisfaction: With no flour, no potatoes, and no bread, it keeps carbs low while still delivering that indulgent, cheesy comfort.
• Protein-forward: Beef provides high-quality protein for satiety and muscle support.
• Flexible for the family: Non-keto eaters can add a toasted baguette slice on the side, while you keep it bowl-only.
• Hands-off cooking: Minimal prep and the slow cooker does the heavy lifting, making it ideal for busy days.

Pitfalls to Watch Out For

• Overcooking on High: High heat for too long can toughen the meat. Stick to Low for the most tender results.
• Boiling after adding dairy: Rapid boiling can cause the cheese to split.

  Keep the heat gentle when finishing the soup.

• Too salty broth: Broth and cheese add salt. Use low-sodium broth and season at the end to avoid oversalting.
• Thickening surprises: The soup thickens as it cools. Reheat with a splash of broth or cream to bring it back to your ideal consistency.

Alternatives

• Different cheeses: Swap provolone with mozzarella for extra stretch, or add a bit of white American or Monterey Jack for creaminess.

  A touch of Parmesan boosts umami.

• Beef swaps: Use thinly sliced deli roast beef in a pinch, adding it during the last 30 minutes so it doesn’t dry out. Ground beef works too—brown it first and drain.
• Dairy-free: Use full-fat coconut milk and a dairy-free cream cheese alternative. Choose a melty dairy-free cheese that fits your plan.
• Add heat: Stir in red pepper flakes or sliced jalapeños.

  A splash of hot sauce at serving also works.

• Extra veggies: Add zucchini slices or riced cauliflower during the last hour to keep them from getting mushy.

FAQ

Is this soup really keto-friendly?

Yes. It skips flour, potatoes, and bread. The main carbs come from onions, peppers, and mushrooms, which are kept moderate.

Always check your specific ingredients and serving size to fit your macros.

Can I make it on the stovetop instead of a crockpot?

Absolutely. Sauté the veggies in a large pot, add beef and broth, then simmer gently for 45–60 minutes until tender. Reduce heat to low and stir in cream cheese, cream, and provolone until smooth.

What cut of beef works best?

Sirloin is tender and quick-cooking.

Chuck roast becomes incredibly tender with low-and-slow cooking. Flank steak also works if sliced thin against the grain. Choose what fits your budget and time.

How can I prevent the cheese from getting stringy?

Add dairy at the end on low heat and avoid boiling.

Cut the cream cheese into small cubes so it melts evenly, and add provolone in batches while stirring.

Can I make it ahead?

Yes. It tastes even better the next day. Reheat gently and thin with a splash of broth or cream if it thickens too much in the fridge.

What can I serve with it to keep it keto?

Try a simple green salad, roasted broccoli, or garlic butter sautéed zucchini.

For crunch, top the soup with crispy bacon bits or toasted almond slices.

How do I lower the calories without adding carbs?

Use a leaner cut of beef, reduce the heavy cream slightly, and rely more on broth. Keep the cheese moderate and boost volume with extra mushrooms or zucchini.
