Saucy penne pasta with pepperoni, Italian sausage and mozzarella cheese. A fast and easy recipe!


  • 1 pound ground Italian sausage
  • 1 cup diced onion
  • 2 tsp minced garlic
  • 1 3/4 cups chicken or beef broth
  • 8 oz uncooked penne pasta
  • 2 (14 oz ) jars pizza sauce (or a 28 oz jar of pasta sauce)
  • 2 tsp Italian seasoning
  • 2 oz sliced pepperoni (about a half cup)
  • 1/2 cup grated mozzarella cheese
  • 1/4 cup shredded parmesan cheese


  1. Turn Instant Pot to sauté setting. When display says HOT add in the sausage and break it up*. Add in the onion. Brown the sausage for about 5 minutes. Add in garlic and sauté for 30 seconds. Drain any grease.
  2. Add in the broth and scrape the bottom of the pot so that nothing is sticking. 
  3. Add in the pasta and press to submerge as much as possible but do not stir. 
  4. Dump the pizza sauce over the pasta. Sprinkle the Italian seasoning over the sauce. Layer the pepperoni over the top. Don’t stir. 
  5. Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 4 minutes. When time is up let the pot sit for 5-10 minutes and then move the valve to venting. Remove the lid.
  6. Sprinkle cheeses on top and let melt. Stir and serve. 


I used my 6 quart Instant Pot Duo 60 7 in 1*. Make in the 8 or 3 quart pot with no changes.
