Ingredients for Pepper Steak Recipe with Mashed Potatoes

Simple ingredients for tender beef and fluffy mashed potatoes in one pan.

The steak is everything here. Ribeye stays juicy and has the right fat marbling for flavor. Most butchers at Whole Foods or Publix will slice it into strips for you if you ask nicely. Look for bright red color with white fat streaks—not brown or gray. For the potatoes, Russets give that classic fluffy texture, but Yukon Golds work too (they’re creamier, which some folks prefer).

No ribeye? Sirloin or flank steak are solid backups, just slice against the grain. Swap soy sauce for coconut aminos if you need gluten-free. Whole milk not on hand? Half-and-half or cream gets you even richer potatoes. The bell pepper can be red or yellow instead of green for a sweeter take. Fresh garlic is best, but 1 tsp of garlic powder in a pinch works.

Leftovers keep 3-4 days in the fridge—steak reheats best in a skillet with a splash of broth. Mashed potatoes thicken when cold, so stir in a little warm milk before serving again. Freezes well too (steak and potatoes separately) for up to 3 months.

Step-by-Step Instructions for Pepper Steak With Mashed Potatoes

Here’s the method. Straightforward, tested, works every time.

Step 1: Cook the Ribeye Steak and Vegetables

Heat the 2 tbsp olive oil in a large skillet over medium-high heat until shimmering. Add the 1.5 lb Ribeye Steak strips and cook for 3-4 minutes until browned on all sides. Remove the ribeye and set aside.

In the same skillet, add the 1 whole Onion and 2 whole Green Bell Pepper strips. Cook for 5-6 minutes until the vegetables are tender and slightly caramelized. Stir occasionally to prevent burning.

Step 2: Create the Pepper Steak Sauce

Add the 4 cloves Garlic Cloves to the skillet and cook for 30 seconds until fragrant. Stir in the 1.5 tbsp Black Pepper and 2 tbsp All-Purpose Flour, cooking for 1 minute to form a roux.

Pour in the 0.33 cup Soy Sauce and 1 cup Beef Broth, stirring constantly. Bring the mixture to a simmer and cook for 3-4 minutes until the sauce thickens enough to coat the back of a spoon. Return the ribeye to the skillet and stir to coat.

Step 3: Prepare the Creamy Mashed Potatoes

While the sauce simmers, place the 2 lb Russet Potatoes in a pot of salted water. Bring to a boil and cook for 15-20 minutes until the potatoes are fork-tender. Drain well and return to the pot.

Add the 0.5 cup Unsalted Butter and 0.75 cup Whole Milk to the potatoes. Mash until smooth and creamy, ensuring there are no lumps. Season with the 1 tsp Salt to taste.

Step 4: Serve and Garnish

Spoon the creamy mashed potatoes onto serving plates. Top with the pepper steak and sauce. Garnish with the 0.25 cup Fresh Parsley for a fresh pop of color and flavor.

Let the dish rest for 2-3 minutes before serving to allow the flavors to meld together. The steak should be tender and covered in a rich, peppery sauce, while the mashed potatoes should be smooth and velvety.

Regional Styles of pepper steak recipe with mashed potatoes

Chinese-Inspired Pepper Steak

This version leans into bold Asian flavors. Use light soy sauce instead of regular and add 1 tbsp oyster sauce to the pan sauce. I also toss in 1 tsp grated ginger with the garlic for extra depth. The result is a savory-sweet sauce that pairs beautifully with steamed jasmine rice too. 🌟

Southern Black Pepper Style

For a Southern twist, swap green bell peppers for poblano peppers and use 2 tsp Cajun seasoning with the black pepper. I like to deglaze the pan with ½ cup bourbon before adding the beef broth—it adds a smoky richness that’s pure comfort food.

French Peppercorn Sauce

This elegant take uses green peppercorns instead of black. After cooking the steak, add 1 tbsp brandy to the pan, then stir in ½ cup heavy cream with the beef broth. The creamy sauce feels restaurant-worthy but takes just 5 extra minutes. I finish with a pat of cold butter for shine.

Texas Chili Pepper Version

Kick up the heat with 1 chopped jalapeño and 1 tsp cayenne in addition to the black pepper. Use chipotle peppers in adobo (minced) for a smoky depth. This version pairs well with the mashed potatoes or even over grits for a Texas-style breakfast. 🔥

Midwest Creamy Pepper

For a heartier sauce, stir in ¼ cup sour cream at the end. This Midwestern approach creates a tangy, velvety coating for the steak. I also add 1 tsp Worcestershire sauce to deepen the umami notes. It’s rich, so serve with extra napkins!
