6 medium mushrooms (about 8 oz / 250 g), diced
3-5 cloves garlic, minced
1-2 tbsp (14-28 g) butter
2 tsp Italian seasoning
2 tbsp (30 g) tomato paste
2/3 cup (150 ml) tomato passata
Salt and pepper to taste
Pinch of sugar, if needed

Handful shredded Mozzarella cheese (to stir into the filling)

3 tbsp (40 ml) hot milk or half and half
1 cup (100 g) finely shredded Cheddar cheese
Pinch of nutmeg
About 2 cups (200-250 g) shredded Mozzarella cheese for topping

For the side salad:

1-2 tbsp lemon juice
Salt and pepper, to taste

Kitchen Tools Needed

Baking dish
Large pot for boiling potatoes
Skillet for sautéing
Mixing bowls
Potato masher
Knife and chopping board

Step-by-Step Instructions

Preheat your oven to 375°F (190°C). Cut off the tops of the bell peppers, remove the cores and seeds, and level the bottoms slightly to help them stand upright without cutting through. Save the tops for later use.
In a skillet over medium heat, brown the Italian sausage. Once cooked, transfer it to a bowl. In the same pan, add a little oil, then sauté the diced onion, saved pepper tops, and mushrooms until they are softened and any moisture has evaporated.
Add the butter, garlic, and Italian seasoning to the center of the skillet. Cook for about 1 minute, then stir in the tomato paste for 1-2 minutes before adding the tomato passata. Season with salt, pepper, and a pinch of sugar, if needed. Return the sausage to the skillet, simmering for another 2-3 minutes until thickened. Off the heat, stir in the shredded Mozzarella until melted.
Meanwhile, boil the potatoes in salted water until tender. Drain and let them steam dry. Mash with the melted butter and hot milk until smooth. Stir in the Cheddar cheese, nutmeg, salt, and pepper, keeping the mash thick.
Carefully fill each pepper with the sausage mixture, pressing down gently and leaving about an inch of space at the top for the mashed potatoes. Top each pepper with the mashed potatoes and use a fork to rough up the tops, which will help them crisp up as they bake.
Place the filled peppers in a baking dish and cover with foil. Bake for 25-30 minutes. Remove the foil, sprinkle the remaining Mozzarella and Parmesan cheese on top, and bake for an additional 10-15 minutes. For an extra crispy topping, broil for the last 1-2 minutes.
Allow the peppers to rest for 5-10 minutes before serving.

Pro Tips

When browning the sausage, ensure the pan isn’t overcrowded; this helps it brown nicely instead of steam.
For a spicier kick, consider using hot Italian sausage.
Give the mashed potatoes a good stir to achieve a smooth consistency—avoid over-mixing, or they can become gummy.

Common Mistakes

Don’t overcook the sausage; it should be browned but not dry.
Ensure you don’t overboil the potatoes; they just need to be fork-tender.
Leave enough space in the peppers when filling so the mash won’t overflow during baking.

Variations

Swap out the Italian sausage for ground turkey or beef for a different flavor.
Add cooked quinoa or rice to the filling for added texture and nutrition.
Spice them up with some diced jalapeños or a spoonful of red pepper flakes.

Serving Suggestions

Serve hot, garnished with parsley for a fresh touch. Pair with a simple side salad for a balanced meal.

Storage Instructions

Store any leftovers in an airtight container in the fridge for up to 3 days.

Reheating Tips

Reheat in the oven at 350°F (175°C) until warmed through, about 15-20 minutes, to help maintain the texture.
