Servings 4

4 large bell peppers (any color), tops cut off and seeds removed
1 lb raw shrimp, peeled and deveined, chopped roughly
1 medium zucchini, finely diced
1 small red onion, finely chopped
2 cloves garlic, minced
1 cup crumbled feta cheese
1/4 cup chopped fresh parsley
1/4 cup chopped fresh dill
1 tbsp olive oil
1 tsp smoked paprika
1/2 tsp dried oregano
Salt and freshly ground black pepper, to taste
1/2 cup low-sodium vegetable broth
2 tbsp lemon juice
Red pepper flakes (optional, for mild heat)

Ingredients for Instant Pot Low-Carb Pescatarian Stuffed Peppers

Instructions

Set the Instant Pot to 'Sauté' mode and heat olive oil. Add chopped red onion and minced garlic, cooking until translucent and fragrant, about 3 minutes.
Add diced zucchini, smoked paprika, dried oregano, salt, and pepper. Sauté for an additional 3 minutes, stirring occasionally until zucchini is slightly softened.
Turn off 'Sauté' mode and transfer the cooked vegetables to a bowl to cool slightly.
In the same bowl, mix the sautéed vegetable mixture with chopped shrimp, crumbled feta cheese, fresh parsley, dill, lemon juice, and red pepper flakes if desired. Stir well until combined evenly.
Generously stuff each hollowed bell pepper with the shrimp and vegetable filling, pressing down gently to fill completely.
Pour 1/2 cup low-sodium vegetable broth into the Instant Pot’s inner pot. Place the stuffed peppers upright on the included steamer rack or trivet inside the pot.
Secure the Instant Pot lid, set the valve to 'Sealing,' and cook on 'Manual' or 'Pressure Cook' at high pressure for 8 minutes.
When cook time ends, allow a natural pressure release for 5 minutes, then carefully perform a quick release for any remaining pressure.
Remove the stuffed peppers carefully from the pot. Spoon any cooking liquid over the peppers for added moisture and flavor.
Serve the stuffed peppers warm, garnished with extra fresh parsley or a squeeze of lemon if desired.
