Step 1

Heat Instant Pot to “Sauté.” Add oil, sausage, and onion. Cook, breaking up sausage into small pieces, until sausage is no longer pink and onions are translucent. Add garlic and cook for 1-2 minutes or until garlic is fragrant.

Step 2

Add chicken broth, pasta, diced tomatoes, and oregano. Stir to combine and make sure pasta is submerged in liquid.

Step 3

Set Instant Pot to “Manual” for 5 minutes. Turn valve to Seal. When the timer goes off, turn valve to Vent to Quick release the pressure.

Step 4

Keep Instant Pot on Warm and add spinach and place cover on (don’t turn to latch). Let wilt for 2-3 minutes, stirring as needed to help it along.

Step 5

Add 1 cup mozzarella cheese and stir to melt. If the sauce appears thin, let set for 5-10 minutes, it will thicken.
