Instant Pot Reuben Casserole

Whenever I go to a deli for lunch the sandwich that always tempts me is the Reuben. It’s got slices of rye bread piled with corned beef, sauerkraut, swiss cheese and thousand island dressing. The best Rueben sandwiches are grilled or put in a panini press. It’s not something I eat very often but I do love it! I love the tanginess from the sauerkraut.

If you’re a fan of the Rueben sandwich you’ll most likely love this Rueben casserole. It’s got potatoes, corned beef, sauerkraut, swiss cheese and sour cream. It only has a few ingredients but has a lot of flavor from the kraut and the corned beef. Try mixing it up with something different tonight for dinner!

Ingredients/Substitution Ideas

• Chicken broth–or 1 cup water and 1 teaspoon of Better than Bouillon Chicken Base
• Red potatoes–or Yukon golds or peeled Russets
• Dehydrated onion flakes–or 1 teaspoon of onion powder
• Garlic powder
• Salt and pepper
• Sauerkraut–or you can use chopped cabbage although it won’t have the flavor intensity of kraut
• Corned beef–or pastrami or ham
• Sour cream–or plain yogurt
• Cornstarch–to thicken the sauce
• Swiss cheese–or another cheese like mozzarella
• Rye bread–optional for the rye bread croutons
• Olive oil–optional for the rye bread croutons

Steps to make Instant Pot Reuben Casserole

1. Dump ingredients into the Instant Pot: Pour broth into Instant Pot. Add in the potatoes, onion flakes, garlic powder. Lightly sprinkle the potatoes with salt and pepper. Dump sauerkraut and corned beef on top.
2. Pressure cook: Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 3 minutes. When time is up you can perform a quick release immediately or you can let the pot sit for 5-10 minutes and then move valve to venting. Remove the lid.
3. Make croutons (optional): If you’d like to make the rye bread croutons then heat oil over medium high heat in a pan on the stove. Cut the rye bread into cubes and toss into the oil until browned and crispy. Set aside. (I made the croutons but personally I don’t think they are necessary)
4. Temper the sour cream: Stir a half cup of the hot liquid from the pot into the sour cream to temper it (this will prevent it from separating). Stir the cornstarch into the sour cream until smooth. Stir the sour cream mixture into the Instant Pot. Turn Instant Pot to sauté setting. When sauce has thickened turn off sauté setting. 
5. Swiss it up: Stir the cheese into the Instant Pot. 
6. Serve: Scoop onto plates and top with croutons (if you made them). If desired, drizzle with a bit of thousand island salad dressing to make the Rueben sandwich experience complete.

Notes/Tips

• To make with rice instead of potatoes: If you’re more a rice person than a potato person try adding in 1 ½ cups of broth and 1 cup of raw long grained white rice instead of the potatoes and 1 cup of broth. Pressure cook for 3 minutes with a 10 minute natural pressure release. Leave out the cornstarch.
• I used my 6 quart Instant Pot. You can also make in a 3 or 8 quart pot.
• No corned beef? Try using pastrami, ham or smoked sausage instead.
• Gluten-free: make this gluten-free by leaving out the rye bread croutons.
• Leftovers: store leftovers in an airtight container* in the refrigerator for up to 5 days or in the freezer for up to 3 months.
