Pepper Beef & Mushroom Skillet – Easy 30-Minute Dinner

This pepper beef and mushroom skillet is the kind of dinner you make when you want something hearty without a pile of dishes. It's all made in one pan, and it's on the table in about half an hour.

The sauce is savory and rich, with a good kick of cracked black pepper that warms you up. The mushrooms get golden and meaty, and the beef stays tender if you don't overcook it.

I like to serve it over mashed potatoes or egg noodles, but rice works great too. It's comfort food that doesn't take all evening.

About the Ingredients

1 1/2 lbs (680g) beef sirloin or flank steak, thinly sliced

Thin slices cook fast. If you buy pre-cut stir-fry strips, they work too. For easier slicing, pop the beef in the freezer for 15 minutes first.

2 tablespoons olive oil, divided

You'll use some for browning the beef and some for the mushrooms. If you don't have olive oil, any neutral oil like canola or vegetable works.

1 lb (450g) cremini or button mushrooms, sliced

Cremini (baby bellas) have more flavor, but button mushrooms are fine. Slice them about 1/4-inch thick so they brown nicely.

2 cloves garlic, minced

Fresh garlic adds a punch. If you're in a hurry, use 1/2 teaspoon garlic powder instead.

1 cup (240ml) beef broth

Use low-sodium if you can, so you control the salt. Chicken broth or even water with a bouillon cube will do in a pinch.

1/2 cup (120ml) heavy cream

This makes the sauce creamy. For a lighter version, use half-and-half, but the sauce won't be as thick. Coconut milk also works for a dairy-free twist.

1 tablespoon Worcestershire sauce

Adds a savory, tangy depth. If you don't have it, skip it or use a splash of soy sauce.

1 teaspoon cracked black pepper, plus more for serving

This is the star. Cracked pepper gives you little bursts of heat. If you only have ground, use 3/4 teaspoon.

1/2 teaspoon salt

Adjust to taste. If your broth is salty, you might need less.

1 tablespoon butter

Stirred in at the end, it makes the sauce glossy and rich. You can skip it, but it's worth it.

Fresh thyme sprigs for garnish (optional)

A few leaves add a fresh, herbal note. Dried thyme works too – add 1/4 teaspoon with the broth.

Step-by-Step Instructions

1. Slice the beef

If the beef isn't pre-sliced, cut it against the grain into thin strips, about 1/4-inch thick. Season with a pinch of salt and pepper.

2. Brown the beef

Heat 1 tablespoon of oil in a large skillet over medium-high heat. Add half the beef in a single layer. Cook without moving for 2 minutes, until browned. Flip and cook 1 more minute. Transfer to a plate. Repeat with the rest of the beef.

3. Cook the mushrooms

Add the remaining oil to the same skillet. Add the mushrooms and spread them out. Let them cook for 3-4 minutes without stirring, until they start to brown. Then stir and cook 2-3 minutes more. They will release liquid, then it will evaporate.

4. Add garlic and seasonings

Stir in the garlic and cook for 30 seconds until fragrant. Sprinkle the cracked pepper and salt over the mushrooms and stir to coat.

5. Make the sauce

Pour in the beef broth and Worcestershire sauce. Scrape up any browned bits from the bottom of the pan. Bring to a simmer and let it cook for 2-3 minutes, until it reduces slightly.

6. Add cream and beef

Lower the heat to medium-low. Stir in the heavy cream. Return the beef and any juices to the pan. Let everything simmer gently for 2-3 minutes, until the sauce thickens just a bit and the beef is heated through.

7. Finish with butter

Turn off the heat. Stir in the butter until it melts into the sauce. Taste and add more salt or pepper if you like.

8. Serve

Serve hot over rice, mashed potatoes, or noodles. Garnish with fresh thyme if you have it.

Tips & Tricks

• Don't crowd the pan when browning the beef. If you add too much at once, it steams instead of browning. Work in two batches if needed.
• Cut the beef against the grain. Look at the lines in the meat and slice across them. This makes the beef tender, not chewy.
• Resist stirring the mushrooms too often. Let them sit for a few minutes to get golden edges. That's where the flavor is.
