Ingredients You’ll Need

• 4 large russet potatoes: The sturdy, fluffy base for our stuffed dinner.
• 2 cups cooked steak, chopped into bite-sized pieces: Our star ingredient! Use any leftover steak you have.
• 1 tablespoon olive oil: For getting our onions nice and soft.
• 1 medium yellow onion, thinly sliced: Adds a sweet, savory depth.
• 1 cup beef broth: Brings moisture and rich flavor to the filling.
• 1 teaspoon Worcestershire sauce: That secret umami kick.
• 1 ½ cups shredded cheddar cheese: Because everything is better with melty cheese.
• ½ cup sour cream: For a cool, creamy finish.
• 2 tablespoons chopped fresh chives: A fresh pop of color and flavor.
• Salt and black pepper to taste: Essential for seasoning every layer.

Let’s Get Cooking Step by Step

1. Heat your oven to 400°F (200°C). Scrub the potatoes clean, pat them dry, and prick them all over with a fork. This lets the steam escape so they don’t burst. Place them directly on the oven rack and bake for 50-60 minutes, until you can easily pierce them with a knife.
2. While the potatoes bake, heat the olive oil in a large skillet over medium heat. Add the sliced onions and cook for about 7-8 minutes, stirring occasionally, until they’re soft and translucent.
3. Add the chopped leftover steak to the skillet with the onions. Pour in the beef broth and Worcestershire sauce. Let this simmer for about 5 minutes, until the liquid reduces slightly and the steak is warmed through. Season with a good pinch of salt and pepper.
4. Once the potatoes are done, carefully slice each one open lengthwise. Use a fork to fluff up the insides. Divide the steak and onion mixture evenly among the potatoes, piling it high.
5. Top each loaded potato with a generous handful of shredded cheddar cheese. Pop them back into the oven for just 3-5 minutes, until the cheese is perfectly melted and bubbly.
6. Finish them off with a dollop of sour cream and a sprinkle of fresh chives right before serving.

Leftover Steak Recipes to Try

If you find yourself with more leftover steak, don’t let it go to waste! There are so many fantastic and easy leftover steak recipes out there. Whip up a quick Philly-inspired leftover steak sandwich with sautéed peppers and provolone on a hoagie roll. Toss thin slices into a salad for a protein boost. Or, one of my personal favorite leftover steak dinner ideas is a hearty steak pasta. Just slice it thinly and toss it with warm pasta, a little butter, garlic, and Parmesan cheese. The options are endless!

Serving Ideas & Pairings

This stuffed baked potato is a full meal all on its own, but it’s always nice to have a little something on the side. A simple, crisp green salad with a light vinaigrette helps cut through the richness. For something heartier, roasted asparagus or green beans make a wonderful veggie side. And if you’re serving a crowd? A basket of warm, crusty bread is never a bad idea for sopping up any delicious juices.

Variations & Substitutions

This recipe is wonderfully flexible. Don’t have cheddar? Try Monterey Jack, pepper jack for a little spice, or even Swiss cheese. For a lighter version, Greek yogurt is a great stand-in for sour cream. If you want to add more veggies, stir some chopped mushrooms or bell peppers into the skillet when you cook the onions. And if you’re looking for other meals with leftover steak, this filling would also be amazing stuffed inside a bell pepper or even rolled up in a warm flour tortilla for a steak burrito.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, the microwave works in a pinch (about 2 minutes on high), but for the best results, pop it back in a 350°F oven for 10-15 minutes until heated through. This helps the potato skin stay nice and the cheese get melty again. I don’t recommend freezing the fully assembled potato, as the potato texture can become watery.
