Heat olive oil in the Instant Pot on the “Saute’ setting. Add the ground beef and brown for a couple of minutes while breaking it up with a spatula. Drain excess fat. The meat doesn’t have to be cooked through and it’s okay if there are red spots.

Add chopped onion, carrots, red bell pepper, and saute for a couple of minutes until vegetables are tender. Add minced garlic, salt, black pepper, Italian herb seasoning, and tomato sauce. Stir everything until combined.

Close the lid and turn the valve to ‘Sealing’. Pressure cook the bolognese sauce for 10 minutes. When finished cooking, quick-release pressure according to manufacturer’s directions.

Taste and adjust the seasoning if necessary.

Serve over cooked spaghetti or pasta, and garnish with chopped fresh parsley.
