Instant Pot Hot Beef and Cheese Sandwich
When you make something with mushrooms in it and your kid who “doesn’t like mushrooms” eats it happily you’re winning! Haha! I did a sneaky mom thing. I chopped up the mushrooms in this hot beef sandwich and my kid didn’t even know. Everyone LOVED these sandwiches. The filling is soooo yummy.
- Make this hot beef and cheese sandwich filling in the Instant Pot or slow cooker it’s up to you. For the slow cooker version you won’t need the broth or the cornstarch.
- You can use lean ground beef or ground turkey
- Montreal steak seasoning gives the beef really good flavor. If you don’t have this seasoning on hand you can make your own.
- By chopping up the mushrooms you can hide them from the kids. Plus it bulks up the recipe without adding extra meat.
- I cut the green peppers in a larger chop because I didn’t want them to disintegrate after being pressure cooked.
- Use any kind of cheese that you like. Try monterey jack, pepper jack, colby, sharp cheddar etc.
- You can serve this on buns, rolls, lettuce wraps or over rice. It’s all good!
- I used my 3 quart pot. This works in the 6 or 8 quart pot as well. I only used a half cup broth because the mushrooms release a lot of moisture. If you’re worried about your pot coming to pressure add in an extra half cup of broth.
- This recipe is easy to double or triple! Keep the same amount of broth if you double it (but double all the other ingredients). And use cornstarch to thicken only as needed.
- Make it instead of sloppy joes at a family dinner!
- Store leftover meat filling in an airtight container in the refrigerator for up to 5 days or in the freezer for up to 3 months.

Did it last night on IP and it was great. Definately one to do again. Thanks.
Thanks Peter!
This is another winner, Karen! I made this tonight and we really enjoyed the rich flavor of the meat. The only thing I did differently was to not add the cheese, but just let each person add their own to the top….saves me calories!
Good plan Kathy! Glad you loved it!
The Hubby declared this one a definite keeper! And I didn’t even have to chop up the mushrooms! 😂
★★★★★
Nice! It really is so tasty! Glad you didn’t have to chop the mushrooms either!
I followed this recipe exactly and also added a sliced up Serrano pepper with the bell pepper. This turned out really good. I’ll probably use the leftover meat for nachos.
★★★★★
mmmm nachos!!!
Im guessing that this can be made stovetop with basically the same method? Looks really good!
★★★★★
Yes for sure…like sloppy joes
