Summer Company Casserole

Summer Company Casserole

This is a great summer dinner for company because it feeds a crowd without heating up the kitchen or keeping you stuck at the stove. Everything cooks in one pot, which means less cleanup and more time to visit with your guests. The flavors are familiar so it’s a meal that both kids and adults tend to enjoy. I especially like it for summer because it incorporates seasonal zucchini and corn, giving it a fresher taste.

Ingredients/Substitution Ideas

  • Lean ground beef–or ground pork
  • Onion–or shallot
  • Kosher salt
  • Garlic powder–or minced fresh garlic
  • Chili powder
  • Cumin
  • Smoked paprika–or regular paprika
  • Dried oregano
  • Black pepper
  • Worcestershire sauce
  • Tomato paste
  • Chicken broth–or beef broth, Better than Bouillon
  • Red wine vinegar–or apple cider vinegar
  • Elbow macaroni–or small shells or rotini
  • Petite diced tomatoes–or crushed tomatoes
  • Tomato sauce
  • Canned corn–or fresh, frozen corn
  • Kidney beans–I used light red kidney beans
  • Zucchini–or yellow squash
  • Cheddar cheese–or Monterey Jack, Colby Jack or Pepper Jack

Steps

Heat Instant Pot to saute setting. When display says HOT add in the beef and break it up. Add in the onion. Brown for 5 minutes, drain off excess grease. Stir in the salt, garlic powder, chili powder, cumin, smoked paprika, oregano, pepper, Worcestershire and tomato paste. 

Pour in the broth and vinegar. Scrape bottom of pot so that nothing is sticking. Turn off Instant Pot. 

Sprinkle in the macaroni. Dump in the tomatoes, tomato sauce, corn and kidney beans.

Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set manual/pressure cook button to 4 minutes. When time is up move valve to venting and remove the lid. 

Stir in the zucchini. Replace the lid. Let the pot sit on the keep warm setting for 5 minutes. 

Remove lid, stir in the cheddar. Serve and enjoy!

Notes/Tips

  • This was a one pot meal for us but if you want a side consider serving with garlic bread and water melon.
  • Stir the zucchini in after pressure cooking so it doesn’t become mushy. Use small diced zucchini or shredded.
  • Freshly shredded cheese melts more smoothly than pre-shredded cheese. If your family loves cheesy meals, increase the cheese to 8 ounces.
  • I used my 4 quart Instant Pot* but it was pretty full. Next time I would cook this in a 6 or 8 quart pot.
  • Store leftovers in an airtight container* in the refrigerator for up to 4 days or in the freezer for up to 3 months.
  • Other recipes you can make with red wine vinegar are No Sneak Casserole and Instant Pot Cafe Rio Black Beans.
