Alfredo sausage stuffed peppers bring together tender bell peppers, savory Italian sausage, and silky Alfredo sauce topped with gooey mozzarella for a main course that satisfies those creamy comfort food cravings. This dish is a weeknight favorite in my home, especially when everyone wants something hearty but just a little different from the usual pasta bakes.
I first started making these peppers as an experiment to use up leftover rice and a jar of Alfredo sauce after a pasta night. Now my family begs for them every time peppers go on sale at the market.
Ingredients
- Bell peppers: fresh and firm peppers are best for stuffing and hold their shape after baking
- Italian sausage: use mild for kids or spicy for a kick look for sausage with plenty of herbs in the mix
- Yellow onion: adds savory sweetness and depth to the filling pick a firm onion with no soft spots
- Garlic: use fresh cloves for the best flavor or try roasted garlic for a mellow note
- White rice: cooked rice helps bind the filling and soaks up Alfredo sauce short or medium grain both work well
- Alfredo sauce: pick a high quality jarred sauce or make your own for extra richness
- Parmesan cheese: adds nutty saltiness freshly grated gives the best flavor
- Mozzarella cheese: melts beautifully choose whole milk mozzarella for perfect stretch
- Fresh parsley: gives a bright finish always use flat leaf for the best flavor
- Dried Italian herbs: brings together classic oregano and basil check the freshness by smelling your jar
- Black pepper: for gentle heat and balance
- Salt: taste the mixture and adjust especially if your sausage is already salty
- Water or chicken broth: for baking to keep the peppers moist and steam them perfectly
Instructions
- Prepare the Peppers:
- Slice the tops off fresh bell peppers and clean out seeds and membranes. Place upright in a baking dish so they sit snug and do not tip over.
- Brown the Sausage:
- Heat a large skillet over medium and add Italian sausage with casings removed. Break up meat as it cooks with a spoon until no pink remains and sausage is browned and fragrant. This browning unlocks deep savory flavor.
- Cook the Aromatics:
- Add finely chopped yellow onion and garlic to the pan with sausage. Cook for several minutes until onion turns translucent and soft, building the aromatic base.
- Make the Filling:
- Stir in cooked rice, Alfredo sauce, half the mozzarella, Parmesan, fresh parsley, dried Italian herbs, black pepper, and a pinch of salt. Mix until everything is well combined and heated through so the flavors meld together.
- Stuff the Peppers:
- Fill each prepared bell pepper generously with the sausage mixture. Gently press the filling to eliminate air pockets so each bite is rich and cohesive.
- Top with Cheese:
- Sprinkle remaining mozzarella over each pepper. This creates a gooey, golden topping during baking.
- Add Liquid and Cover:
- Pour water or chicken broth into the baking dish. This keeps peppers tender and prevents scorching. Cover loosely with foil to help steam them in the first stage of baking.
- Bake to Perfection:
- Place dish in preheated oven and bake for thirty minutes covered. Remove foil and bake another ten minutes uncovered until cheese bubbles and browns and peppers are fork tender.
- Rest and Garnish:
- Let peppers cool slightly after baking so flavors settle. Garnish with extra parsley for freshness before serving.

These peppers hold a special place on my table because Parmesan cheese reminds me of my grandmother’s cellar always stocked with wheels of cheese ready for grating. Whenever I add that snowy layer to the filling I think of her big Italian feasts and laughter filled dinners.
Storage Tips
Refrigerate leftover stuffed peppers in a sealed container for up to three days. For quick lunches slice cold peppers and reheat gently in a microwave or covered in the oven to avoid drying out the cheese and filling.
Ingredient Substitutions
You can absolutely swap in ground chicken or turkey sausage for a lighter profile without losing flavor. For a vegetarian option use sautéed mushrooms and lentils in place of sausage and select a dairy free Alfredo to accommodate allergies. Mozzarella can be swapped for provolone or a sharper white cheddar if you like extra tang.
Serving Suggestions
A crisp green salad with lemon vinaigrette on the side brightens the rich flavors of the stuffed peppers. Garlic bread or a light soup works for a larger meal. Sometimes I serve these as part of a buffet since they hold together perfectly for self serve dinners.
Cultural and Historical Context
Stuffed peppers are a staple in many global cuisines with each region putting its own twist on the classic filled pepper. This version is rooted in Italian American cooking where creamy sauces and gooey cheese shine. The Alfredo touch was my way of making an old school dish feel new and lush.
Seasonal Adaptations
Use red or yellow peppers in the summer for sweetness
Try adding spinach in winter for an extra nutrient boost
Use homemade Alfredo when fresh cream is in season for even deeper flavor
Success Stories
I once brought a tray of these to a friend’s potluck and watched every last pepper disappear before the salads were even touched. Families love how fork tender and creamy they turn out and they always ask for the recipe afterward.
Freezer Meal Conversion
These peppers freeze beautifully before baking. Assemble and fill as usual then wrap tightly with foil and freeze. Bake from frozen adding an extra fifteen minutes to the base covered bake time for a stress free weeknight dinner.

With their gooey cheese, comforting filling, and tips for freezing or adapting, these Alfredo stuffed peppers are ready to become your new family favorite. Enjoy every creamy bite!
