What Ingredients are in Melt-in-Your-Mouth Pepper Steak?
This pepper steak recipe brings together simple, hearty ingredients that transform into something truly magical during the slow cooking process. The foundation of good pepper steak starts with quality sirloin—which becomes tender and succulent after its lengthy stint in the oven.
The combination of sweet onions, bright green peppers, and rich beef gravy creates a symphony of flavors that’s both comforting and satisfying. And the best part? You probably have most of these ingredients in your kitchen already.
- 1 pound sirloin steak
- 1 small onion, sliced
- Salt and pepper to taste
- 2-3 tablespoons butter or margarine
- 1 medium green pepper, sliced
- 1 (12 ounce) jar Heinz beef gravy
- 1/2-1 cup water
- Flour (for thickening)
When shopping for this recipe, quality matters with the sirloin—look for good marbling, which helps keep the meat tender during the long cooking time.
The gravy brand is specified as Heinz, but honestly, any good quality beef gravy will work just fine. And while the recipe doesn’t specify the amount of flour needed for thickening, I typically start with about 2 tablespoons mixed with cold water to make a slurry.
Depending on how thick you like your gravy, you might want to adjust the amount of flour or water in your final dish. Remember, the beauty of comfort food like this is that it’s forgiving and adaptable to your personal preferences.
How to Make this Melt-in-Your-Mouth Pepper Steak

Begin by preheating your oven to 350 degrees. Season 1 pound of sirloin steak with salt and pepper to taste, making sure to coat all sides evenly.
In a hot skillet, melt 2-3 tablespoons of butter and add 1 small sliced onion, sautéing until it begins to soften. Add the seasoned steak to the pan and brown it on all sides, creating that gorgeous caramelization that builds so much flavor. The sizzle of steak hitting a hot pan? That’s the sound of dinner magic happening.
Once your steak is nicely browned, transfer it to a baking dish along with a bit of those flavorful drippings. Arrange 1 medium sliced green pepper around the steak—they’ll infuse the dish with their fresh, slightly sweet flavor as everything cooks.
Pour a 12-ounce jar of Heinz beef gravy over the top, then add about 1/2 to 1 cup of water, just enough to barely cover the ingredients. For perfectly sliced vegetables that cook evenly, consider using a high end food processor to prep your peppers and onions. Cover the dish tightly with foil and pop it in the oven for a full 2 hours. This long, slow cooking process is what transforms that sirloin into fork-tender perfection.
During the last 10-15 minutes of cooking, whisk together some flour and water to create a slurry, then stir it into the cooking liquid and cover again. This final step thickens everything into a luscious gravy that clings beautifully to each bite.
Serve your pepper steak over fluffy rice or tender egg noodles for a comforting meal that’ll have everyone asking for seconds.
Melt-in-Your-Mouth Pepper Steak Substitutions and Variations
While the classic pepper steak recipe creates a tender, flavorful dish that’s hard to improve upon, you’ll be amazed at how many delicious variations you can create with just a few simple swaps.
Try substituting sirloin with ribeye or flank steak for different textures. You can replace green peppers with multicolored bell peppers for a vibrant presentation, or add a kick with jalapeños if you’re feeling adventurous.
Not a fan of jarred gravy? Make your own with beef broth, soy sauce, and a splash of Worcestershire. For a lighter version, swap butter with olive oil and serve over cauliflower rice instead of traditional rice.
What to Serve with Melt-in-Your-Mouth Pepper Steak
Once you’ve mastered the perfect pepper steak, finding the right accompaniments can elevate your meal from simply delicious to absolutely memorable.
The recipe itself suggests serving with rice or egg noodles, and I couldn’t agree more—these starchy bases soak up that rich, savory gravy beautifully.
I’d recommend a jasmine rice for its aromatic qualities, or perhaps buttered egg noodles tossed with a bit of parsley.
A simple side salad with a light vinaigrette provides a revitalizing contrast to the richness of the steak.
Don’t forget crusty bread for sopping up every last drop of that incredible gravy!

I’m convinced there’s nothing more satisfying than watching someone’s eyes light up at that first bite—when the beef practically melts, the peppers offer that perfect slight resistance, and the gravy ties everything together.
