What Goes Into the Pot Today
- 1 tablespoon olive oil that gets everything started with a bit of sizzle.
- 2 pounds of thinly sliced beef that cooks super fast and stays juicy.
- 1 small onion sliced thin for that sweet and savory base flavor.
- 2 bell peppers, sliced thin, for crunch and color.
- 2 cups button or baby bella mushrooms, sliced just the way you want, optional but heck, they add depth.
- 2 cups shredded provolone cheese or slices that melt into fabulous gooeyness.
- 4 ounces cream cheese, because creaminess is non-negotiable here.
- ½ cup beef broth, 1 teaspoon Worcestershire sauce, 1 teaspoon garlic salt, and ½ teaspoon black pepper to tie it all together.

The Exact Process From Start to Finish
Step 1, heat your olive oil right in the pressure cooker on the sauté mode if you have it, or use a skillet. Toss in onions, bell peppers, and mushrooms. Sauté those babies until they get soft and smell super good, about 5 to 7 minutes.
Step 2, add your thinly sliced beef and cook it up till browned. You'll notice that tender pull start happening right away. Stir it around so it doesn't stick.
Step 3, drop in the cream cheese, beef broth, Worcestershire, and garlic salt. Stir until cream cheese melts and everything mixes up into a creamy, tasty sauce.
Step 4, shut off sauté mode and do a quick release to reduce pressure, then transfer everything to a casserole dish. Your pot isn't done yet, just taking a break!
Step 5, pile that shredded provolone cheese all over your beef mixture. Then pop the dish in the oven at 350°F. Bake 15 to 20 minutes until cheese goes all bubbly and slightly browned.

Step 6, pull the casserole out, let it cool just a little. This waiting part's hard but worth it. Then dig in while it's all cheesy, tender, and rich. You're gonna love this comforting feast.
Time Savers That Actually Work
- Pre-slice your veggies and beef ahead of time. You can keep them in the fridge so when dinner time hits, you just dump and go.
- Use pre-shredded provolone. Saves you that extra grating step, and you get even meltiness all over the casserole.
- Cook veggie mix in your pressure cooker sauté feature. That means less pans to wash and almost no extra time wasted transferring stuff around.

Your Leftover Strategy Guide

The FAQ Section You Actually Need
- Can I skip the mushrooms? Totally! Mushrooms add nice flavor and texture but if you don't like 'em or don't have any, you can leave 'em out no problem.
- What's the best beef cut to use? Thinly sliced ribeye or sirloin works great here. More tender cuts make that tender pull happen easy.
- Do I have to bake the casserole? You could skip baking but the cheese topping won't get bubbly and browned. The oven step really finishes it nicely.
- What if I don't have a pressure cooker with sauté? No worries, just use a skillet for the sauté steps then transfer to cooker or bake as written.
- Is this recipe low carb friendly? Yep, it's designed to keep carbs low by sticking to veggies, meat, and cheese, nixing the bread.
- How do I do the quick release properly? Careful opening the valve so the steam doesn't burn you. Use a spoon or towel to lift the valve and let the steam hiss out slowly.
