My dad made a version of this pepper steak for us just last weekend, and I was reminded how a simple pan of beef, peppers, and onions can feel like a full Sunday supper. This is very much a Midwestern, no-fuss kind of recipe: four ingredients, one baking dish, and the oven does the work while you set the table. The meat turns out fork-tender, tucked into a rich brown gravy with soft onions and green peppers, just like the casseroles that showed up at every church potluck when I was raising my kids. It’s the kind of meal you make when you want something comforting and complete without fussing over a dozen little ingredients.
I like to spoon this pepper steak and gravy over a bed of hot mashed potatoes, the way my mother did, so every bit of that brown gravy gets soaked up. Buttered egg noodles or plain white rice work just as well and keep things simple. Add a side of canned green beans or a small tossed salad if you’d like a little color on the plate, and some soft dinner rolls to mop up the extra gravy. A glass of iced tea or a cold glass of milk finishes off this very down-home, stick-to-your-ribs kind of supper.
Oven Baked 4-Ingredient Pepper SteakServings: 4
Ingredients
2 pounds beef sirloin or round steak, cut into thin strips
2 large green bell peppers, seeded and sliced into strips
1 large yellow onion, sliced into thin wedges
2 (10.5-ounce) cans condensed beefy mushroom or brown gravy-style soup
Directions
Preheat your oven to 325°F (165°C). Lightly grease a 9x13-inch glass baking dish so the meat and vegetables don’t stick.
Lay the sliced onion evenly in the bottom of the baking dish. Scatter the sliced green bell peppers over the onions, spreading them into an even layer.
Arrange the beef strips on top of the peppers and onions, spreading them out so they cook evenly. If some pieces overlap a bit, that’s fine.
In a medium bowl, whisk or stir the condensed soup until smooth. You don’t need to add water; you want it thick so it bakes into a rich brown gravy.
Pour the soup evenly over the beef, peppers, and onions, using a spatula or spoon to nudge it into the corners so everything is lightly coated.
Cover the baking dish tightly with aluminum foil. This helps the beef stay moist and turn tender in the oven.
Bake, covered, for 1 1/2 to 2 hours, or until the beef is very tender when you poke it with a fork. Thinner strips will be done closer to 1 1/2 hours; tougher cuts may need the full 2 hours.
Remove the foil and gently stir the beef, peppers, onions, and gravy together so everything is coated and the vegetables are tucked down into the sauce.
If you’d like the gravy a bit thicker, return the dish to the oven, uncovered, for another 10 to 15 minutes. Otherwise, let it rest on the counter for about 5 minutes to settle before serving.
Serve the tender pepper steak and gravy hot, spooned over mashed potatoes, egg noodles, or rice, making sure every plate gets plenty of peppers, onions, and sauce.
Variations & Tips
For a slightly different flavor, you can swap in red or yellow bell peppers for part of the green, though the old-fashioned Midwestern version usually sticks with green for its sturdy flavor. If you prefer a little more body to the gravy, stir in a spoonful of instant mashed potato flakes or a tablespoon of flour into the condensed soup before pouring it over the meat. Tougher, budget-friendly cuts like chuck or bottom round work well here too; just slice them thin and lean toward the longer end of the baking time. You can also prepare this a day ahead: bake as directed, cool, and refrigerate. Reheat covered at 300°F until hot and bubbly; the flavors deepen and the meat gets even more tender. If you need to stretch the meal for extra mouths, add another onion and pepper and serve over a generous bed of potatoes, noodles, or rice so that rich brown gravy goes further.
