Description

A twist on good old fashioned tuna casserole. Flavors from Mom’s tuna casserole but made easier, faster and without cream of soups. 


Ingredients

Scale
  • 1 tsp olive oil
  • 1/4 cup diced onion
  • 1 large garlic clove, minced
  • 1 3/4 cups chicken broth
  • 6 ounces uncooked pasta shells (you can also use elbow macaroni)
  • 1 cup diced mushrooms
  • 1 Tbsp Dijon mustard
  • 1 (5 oz) can tuna, drained
  • 1 1/2 cups grated sharp cheddar cheese
  • 1 cup frozen peas
  • 1/2 cup crushed cornflakes or potato chips
  • Salt and pepper

Instructions

  1. Turn your Instant Pot to the saute setting. When the display says HOT add in the oil and swirl it around. Add in the diced onions and saute for 2 minutes. Then add in the garlic and saute for 20 seconds. Add in the chicken broth and scrape the bottom of the pot. Turn off the Instant Pot.
  2. Add in the pasta, mushrooms, mustard and tuna.
  3. Cover the pot and secure the lid. Make sure the valve is set to sealing. Set the manual/pressure cook button to 3 minutes. When the time is up move the valve to venting. Remove the lid.
  4. Stir in the cheese and peas. Let the pot sit for a minute or two with the lid on top so the peas will warm through and the cheese will melt. It may be a little runny at first but as it sits and you stir it the pasta will soak up the liquid. Salt and pepper to taste.
  5. Then, if desired, you can pour the pasta into a baking dish and bake the cornflakes/potato chips on top for 5 minutes at 400 degrees F. I used my Mealthy CrispLid* to crisp up the cornflakes. I cooked for 3 minutes at 450. 
  6. Scoop onto plates and enjoy! 

Notes

This makes a small batch, 4 servings. You can easily double this recipe. Just double all the ingredients and keep the cooking time the same.
