Ingredients
Method
- Brown the sausage. Heat olive oil in a skillet over medium heat. Add the Italian sausage and break it up with a spoon. Cook until browned and no longer pink, about 6–8 minutes. Drain excess fat if needed.
- Sauté the aromatics. In the same skillet, add onion, bell peppers, and mushrooms. Cook 4–5 minutes until softened. Stir in garlic and cook 30 seconds until fragrant.
- Load the crockpot. Add the browned sausage, sautéed veggies, pepperoni, olives, marinara or crushed tomatoes, broth, tomato paste, Italian seasoning, red pepper flakes, salt, and pepper to the crockpot. Stir well.
- Slow cook. Cover and cook on Low for 6–7 hours or on High for 3–4 hours. The flavors will deepen and the broth will thicken slightly.
- Add the creamy finish. About 30 minutes before serving, whisk the softened cream cheese and heavy cream together in a small bowl until smooth. Stir the mixture into the crockpot. Add half the mozzarella and all the Parmesan. Cover and cook 20–30 minutes until the cheeses melt and the soup turns silky.
- Final seasoning and serve. Taste and adjust salt and pepper. Ladle into bowls, top with the remaining mozzarella, and let it melt. Garnish with chopped basil or parsley and extra pepperoni if you like.

Add the Italian sausage and break it up with a spoon. Cook until browned and no longer pink, about 6–8 minutes. Drain excess fat if needed.
- Sauté the aromatics. In the same skillet, add onion, bell peppers, and mushrooms.
Cook 4–5 minutes until softened. Stir in garlic and cook 30 seconds until fragrant.
- Load the crockpot. Add the browned sausage, sautéed veggies, pepperoni, olives, marinara or crushed tomatoes, broth, tomato paste, Italian seasoning, red pepper flakes, salt, and pepper to the crockpot. Stir well.

Keeping It Fresh
Store leftovers in airtight containers in the fridge for up to 4 days.
The flavors get even better by day two. Reheat gently on the stove over low heat, stirring often to prevent cheese from sticking, or microwave in short bursts, stirring between rounds.
For freezing, cool the soup completely and portion into freezer-safe containers, leaving a little room for expansion. Freeze up to 2 months.
Thaw overnight in the fridge and reheat slowly, adding a splash of broth or cream if it thickens too much.
Benefits of This Recipe
- Low in carbs, big on flavor. You get the pizza experience without the crust or sugar-heavy sauces.
- Hands-off cooking. The crockpot saves time and keeps dinner stress-free.
- High in protein and satisfying fats. Sausage, cheese, and cream keep you full and energized.
- Meal-prep friendly. Makes multiple servings and reheats well.
- Customizable. Swap toppings to match your favorite pie.
What Not to Do
- Don’t use sugary sauces. Many jarred sauces hide added sugar. Check labels and choose a low-carb marinara or plain crushed tomatoes.
- Don’t skip browning the sausage. Browning adds depth and keeps the soup from tasting flat.
- Don’t add dairy too early. Cream and cheeses can separate if cooked too long. Stir them in near the end.
- Don’t overload with salty add-ins. Pepperoni, olives, and Parmesan are salty.
Taste before adding extra salt.
- Don’t crank the heat to speed it up. High heat can curdle dairy and toughen meat. Stick to the recommended times.
Recipe Variations
- Supreme style. Add diced zucchini and a few slices of jalapeño. Use both beef and sausage for a hearty combo.
- Buffalo chicken twist. Swap sausage for shredded rotisserie chicken, add 2–3 tablespoons buffalo sauce, and top with blue cheese crumbles.
- Hawaiian-inspired (keto-friendly). Use Canadian bacon and a few drops of pineapple extract for aroma without the sugar.
Finish with extra mozzarella.
- Veggie-loaded. Skip meat and double mushrooms, peppers, and zucchini. Add a bit more Parmesan for umami.
- Spicy arrabbiata. Use hot Italian sausage, extra red pepper flakes, and a pinch of smoked paprika.
- Dairy-light option. Reduce cream cheese to 2 oz and heavy cream to 1/4 cup. Add more broth for a thinner, brothy finish.
FAQ
Is this soup really keto?
Yes.
It focuses on low-carb vegetables, full-fat dairy, and protein. Be sure to use a no-sugar-added marinara or plain crushed tomatoes and monitor portion sizes of higher-carb veggies if you track macros.
Can I make it on the stovetop?
Absolutely. Brown the meat and sauté veggies in a large pot.
Add sauce, broth, seasonings, pepperoni, and olives. Simmer on low for 30–40 minutes. Stir in the cream cheese, cream, and cheeses at the end until smooth.
What can I use instead of Italian sausage?
Ground beef, ground turkey, or chicken sausage all work.
Just bump up the Italian seasoning and salt to keep the flavor bold.
How do I thicken the soup without flour?
Cream cheese is the keto-friendly thickener here. You can also simmer uncovered for the last 20 minutes to reduce slightly, or add extra shredded mozzarella for body.
What toppings go well on each bowl?
Try extra pepperoni, a sprinkle of red pepper flakes, chopped fresh basil, grated Parmesan, or a dollop of ricotta. A drizzle of olive oil adds a nice finish, too.
Can I make it dairy-free?
Yes, with adjustments.
Use coconut cream instead of heavy cream and skip cheese, or try a dairy-free mozzarella alternative. Expect a lighter, less “pizza-parlor” result, but still tasty.
How spicy is it?
It’s mild as written. Add more red pepper flakes or use hot Italian sausage if you want heat.
What’s the best way to keep pepperoni from getting greasy?
Pat the slices dry with a paper towel before adding to the crockpot, or crisp them in a skillet and drain before stirring in at the end for texture.
Can I add riced cauliflower?
Yes.
Stir in 2 cups of cauliflower rice during the last 30 minutes. It soaks up flavor and adds bulk without many carbs.
How many servings does this make?
About 6 hearty bowls. If you’re serving side salads or other dishes, you can stretch it to 8 smaller portions.
