Top Reasons To Make It
- A Cleanup Dream: Everything cooks in a single skillet, so you can spend less time scrubbing and more time relaxing.
- Zero Waste Wonder: It’s the perfect, most delicious answer to the question of what to do with leftover steak.
- Weeknight Fast: Since the steak is already cooked, this dish comes together in about 30 minutes.

- So Flexible: It’s a fantastic template for clearing out the veggie drawer—bell peppers, onions, corn, you name it!
Ingredients
- 1 tablespoon olive oil: To sauté our veggies.
- 1 medium onion, sliced: For a sweet, savory base.
- 2 bell peppers (any color), sliced: For classic fajita crunch and color.
- 2 cloves garlic, minced: For that essential aromatic flavor.
- 1 tablespoon fajita or taco seasoning: Our flavor powerhouse.
- 8 ounces penne or rotini pasta: Sturdy shapes that hold the sauce well.
- 2 cups beef or chicken broth: The liquid that cooks our pasta and creates the sauce.
- 1 (10 oz) can diced tomatoes with green chiles: Adds a tangy, slightly spicy kick.
- 2 cups cooked steak, sliced into bite-sized strips: Our star ingredient!
- 1/2 cup heavy cream or half-and-half: For a touch of creamy richness.
- Salt and black pepper to taste: To make all the flavors pop.
- Optional toppings: shredded cheese, sour cream, fresh cilantro.
Instructions
- Heat the olive oil in a large, deep skillet or Dutch oven over medium-high heat. Add the sliced onion and bell peppers and cook for 5-7 minutes, until they begin to soften and get those lovely little browned edges.
- Stir in the minced garlic and fajita seasoning and cook for one more minute, until fragrant.
- Add the uncooked pasta, broth, and the can of diced tomatoes with green chiles (do not drain the tomatoes). Give everything a good stir to combine.
- Bring the mixture to a boil, then reduce the heat to a simmer. Cover the skillet and let it cook for about 12-15 minutes, stirring occasionally, until the pasta is al dente and has absorbed most of the liquid.
- Gently stir in the sliced leftover steak and the heavy cream. Cook for another 2-3 minutes, just until the steak is heated through. Be careful not to boil it now that the cream is in. Taste and season with salt and pepper as needed.
- Serve immediately with your favorite toppings. So good.
One Pan Cooking Tips
- Use a pan that’s large enough! You want enough room to comfortably stir all the pasta and veggies.
- Don’t skip the step of sautéing the peppers and onions first. This builds a deeper, sweeter flavor base for the whole dish.
- If the pasta absorbs the liquid too quickly and is still a bit hard, just add a splash more broth or water and continue cooking.
- When you add the steak, just warm it through. Overcooking can make it tough, and we want it to stay tender, so tender.
- For a fun twist, try stirring in a handful of spinach right at the end until it wilts.
Variations & Substitutions
- Gluten-Free: Swap the regular pasta for your favorite gluten-free penne. The cooking time might vary slightly, so check the package instructions.
- Dairy-Free: Omit the heavy cream or use a plain, unsweetened non-dairy milk like oat or cashew milk for a lighter sauce.
- Spice It Up: Add a diced jalapeño with the bell peppers, or add a pinch of cayenne pepper with the seasoning. Honestly, if you love heat, a dash of your favorite hot sauce at the end is perfection.
- Veggie Boost: Feel free to add sliced mushrooms, corn, or black beans when you add the broth.
- Different Protein: This method works beautifully with leftover chicken or even smoked turkey sausage.
Serving Ideas & Pairings
This pasta is a complete meal all on its own, but I love serving it with a simple side salad with a bright lime vinaigrette to cut through the richness. Warm, soft flour tortillas or a pile of tortilla chips for scooping are also a huge hit at my table. And a cold cerveza or a refreshing glass of iced tea pairs wonderfully.
Storage & Reheating
Store any leftovers in an airtight container in the refrigerator for up to 3 days. The pasta will continue to absorb the sauce, so when reheating, add a tablespoon or two of broth or water to a skillet over medium-low heat. Gently warm it, stirring occasionally, until heated through. I don’t recommend freezing this one, as the creamy sauce and pasta can become grainy and mushy upon thawing.
Frequently Asked Questions
- Can I use a different cut of leftover steak? Absolutely! Any cooked steak will work wonderfully here, from flank and skirt steak to sirloin or even the ends of a prime rib.
- My steak is already seasoned. Won’t this be too spicy? It’s a great question. If your steak is heavily seasoned, you might want to reduce the amount of extra fajita seasoning you add by about half, then taste and adjust at the end.
- What other easy leftover steak recipes can I try? This pasta is a favorite, but leftover steak is also fantastic chopped up for quick steak sandwiches, tossed into a hearty salad, or scrambled into eggs for a hearty breakfast.
- Can I make this with uncooked steak? You can, but it changes the recipe. You’d want to cook diced raw steak first, then set it aside and proceed with the recipe, adding it back in at the end. But the beauty of this dish is its simplicity with leftovers!
