Instant Pot Steak Diane Casserole
I got my idea for this recipe from a blog called Kitchen Sanctuary. The original author called this recipe a “casserole.” In my opinion it’s more of a stew or a meaty sauce. Whatever you call it, it is truly delicious. I couldn’t stop sneaking bites of the sauce. It was addicting! I was so full and still couldn’t stop.
Rules were made to be broken and I broke a cardinal Instant Pot rule to get this recipe to work right. The Instant Pot rule that I broke was adding in thickeners/flour before pressure cooking. I did a few workarounds to get it to work and not get the “burn error message.” I was so pleased when I opened up the pot and nothing stuck to the bottom of the pot and scorched. Nothing! Victory!!
How to make Instant Pot Steak Diane Casserole:
- Heat up a pan on the stove and add in the oil and some beef stew meat that has been patted dry. This will help the beef brown better. Brown on one side for about 3-4 minutes and then turn the pieces over and brown on the other side for about 3-4 minutes.
- Sprinkle in salt, pepper and flour. Toss well to coat the meat in the flour.
- Add in mushrooms, onions, tomato paste, vinegar and Worcestershire sauce. Then turn off the stove.
- Here’s the step that’s really important so you don’t get the burn message. Heat the broth in the Instant Pot using the sauté setting until it starts to boil. As it starts to boil dump the contents from the pan into the Instant Pot (don’t stir). Because the liquid is boiling the pot practically stirs itself and the flour won’t adhere to the bottom of the pot and burn. Since the liquid is hot the pot will come to pressure within a minute or two so it won’t have time to burn. WOO HOO!!
- Pressure cook for 15 minutes with a 15 minute (or longer) natural pressure release. This will give you the most tender bites of stew meat ever!
- Stir in cream and cornstarch to thicken the sauce further. Salt and pepper to taste.
- Serve the sauce over mashed potatoes, buttered egg noodles or rice. Enjoy! It really is so tasty. I think you’ll really love it.
