Auntie Lori’s Casserole

This Swedish meatball and potato dinner totally surprised me with how delicious it turned out! I love that it uses frozen meatballs, which makes things so much easier on a busy night. The shredded carrots add such a nice little touch. They add some color and they seem to melt right in and give just the tiniest bit of sweetness. Greg basically camped out by the Instant Pot and ate this until it was completely gone… sorry, Skyler, no leftovers for you! (Recipe adapted from Auntie Lori’s Swedish Meatballs Casserole on Food.com).

Ingredients/Substitution Ideas

  • Olive oil–or butter, canola oil
  • Onion
  • Mushrooms
  • Worcestershire sauce
  • Chicken or beef broth–or water and Better than Bouillon
  • Carrot
  • Frozen swedish meatballs–or frozen homestyle meatballs
  • Russet potatoes–or red potatoes, yukon gold
  • Kosher salt
  • Black pepper
  • Garlic powder
  • Nutmeg
  • Heavy cream–or 1/4 cup sour cream

Steps

Turn Instant Pot to saute setting. When display says HOT add in the oil and swirl around. Add in the onion and mushrooms and saute for 4 minutes.

Pour in the Worcestershire sauce and broth and scrape bottom of pot so that nothing is sticking. Turn off Instant Pot.

Add in the carrots, meatballs and potatoes. Sprinkle the potatoes with the salt, pepper, garlic powder and nutmeg.

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 let pot sit for 5-10 minutes and then move valve to venting. 

Temper the cream by stirring in some of the hot liquid from the Instant Pot into the cream. Then stir the cream into the Instant Pot. Add extra salt to taste, if needed.

Serve and enjoy!

Notes/Tips

  • Serve with steamed green beans or roasted brussels sprouts, a buttered slice of crusty bread also goes nicely with this dinner.
  • Shred the carrot finely. It blends into the sauce better and adds a subtle sweetness without changing the texture.
  • Temper the cream slowly. This step keeps the cream from curdling when it hits the hot liquid. Stirring in a little hot broth first makes all the difference.
  • I used my 6 quart Instant Pot*. You can also make this in a 3 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 carrot are Instant Pot Broccoli Cheddar Soup and Road Rage Casserole.

    We loved this one….husband raved about it! I was surprised because I’ve tried frozen meatballs before and didn’t like them, but these tasted good in this recipe, maybe because they were Swedish meatballs. Will make again.

    Winner Winner! Meatball dinner! My husband said on a scale of 1-10…it’s a 25! I made enough for my in-laws and they said “You’re welcome to cook for us anytime if it’s this good”! The nutmeg was subtle but a great surprise addition. Thank you for another FABULOUS recipe!

    Ha! Ha! Looks like The Gregster has finally gone on the offense against that bottomless pit, Skyler. At least until tomorrow when the IP cranks up again, and Skyler manages to get there first. Love it!

      ha! you are right. Skyler is home typically before Greg and always gets first dibs. Lucky for Greg on this day he beat him to it.
