If you love party appetizers that taste indulgent but can still fit a low-carb or keto plan, these stuffed mushrooms with sausage deliver big flavor in a small package. Juicy cremini caps are filled with savory Italian sausage, creamy cheese, garlic and herbs — baked until golden. They’re easy to assemble, impressive on a platter, and surprisingly keto-friendly.
Why this recipe works
- High fat, moderate protein and low net carbs — ideal for keto/low-carb menus.
- Rich texture from cream cheese and Parmesan, with meaty, herby depth from Italian sausage.
- Versatile: swap pork for turkey sausage for fewer calories, or use pork rinds/breadcrumbs if you’re not low-carb.
Yield: about 12 large stuffed mushrooms (appetizer serving = 3 mushrooms)
Prep time: 15 minutes
Cook time: 20–25 minutes
Total time: 35–40 minutes
Ingredients
- 12 large cremini (or white) mushroom caps, stems removed and reserved
- 8 oz (227 g) bulk Italian sausage (mild or spicy), casing removed
- 4 oz (113 g) full-fat cream cheese, softened
- 1/4 cup (25 g) grated Parmesan cheese
- 1/4 cup (28 g) almond flour (for keto) or 1/4 cup plain breadcrumbs (if not low-carb)
- 1 small shallot, finely minced
- 2 cloves garlic, minced
- 2 tbsp fresh parsley, chopped (plus extra for garnish)
- 2 tbsp olive oil, divided
- Salt and freshly ground black pepper, to taste
- Optional: pinch of red pepper flakes or 1/2 tsp Italian seasoning
Step-by-step instructions
- Preheat and prep: Preheat oven to 400°F (200°C). Clean mushroom caps with a damp towel; remove stems and finely chop the stems to use in the filling.
- Sauté aromatics: Heat 1 tbsp olive oil in a skillet over medium heat. Add minced shallot, chopped mushroom stems and garlic; sauté 2–3 minutes until softened.
- Cook sausage: Add Italian sausage to the skillet, breaking into small pieces. Cook until browned and cooked through (about 6–8 minutes). Drain any excess fat if desired (for a lower-fat version).
- Make the filling: Transfer sausage mixture to a bowl and let cool slightly. Stir in cream cheese, Parmesan, almond flour, parsley, salt and pepper until well combined. Adjust seasoning.
- Stuff mushrooms: Brush mushroom caps lightly with remaining olive oil and place on a baking sheet, cavity up. Spoon the sausage mixture into each cap, heaping evenly.
- Bake: Bake 15–20 minutes, until filling is hot and tops are golden. For extra color, broil 1–2 minutes at the end — watch closely to avoid burning.
- Serve: Garnish with extra chopped parsley and serve warm.

How this fits a keto/low-carb diet
- With roughly 5.7 g net carbs per 3-mushroom serving, these stuffed mushrooms are a keto-friendly appetizer when portioned sensibly.
- Fiber (from almond flour and mushrooms) helps reduce net carbs. If you replace almond flour with regular breadcrumbs, expect net carbs to rise significantly (roughly +3–5 g net carbs per serving, depending on breadcrumb quantity).
Tips and variations
- Lower fat: Use turkey Italian sausage or partially drain cooked sausage to reduce overall fat and calories.
- Gluten-free: Almond flour keeps this gluten-free; use gluten-free breadcrumbs if you prefer that texture.
- Extra crunchy topping: Sprinkle crushed pork rinds or extra Parmesan on top before baking for a crisp finish (pork rinds keep it keto).
- Make-ahead: Prepare filling and stuff mushrooms but don’t bake. Cover and refrigerate for up to 24 hours; bake when ready.
- Vegetarian version: Replace sausage with crumbled tempeh or finely chopped walnuts + smoked paprika + tamari for a savory, low-carb vegetarian option.
Storage and reheating
- Refrigerate leftovers in an airtight container for up to 3 days. Reheat in a 350°F (175°C) oven for 8–10 minutes or until warm. Avoid microwaving if you want to preserve texture.

Stuffed mushrooms with sausage bring savory, cheesy comfort to any gathering while staying compatible with low-carb and keto lifestyles when made with almond flour and portioned sensibly.
