This oven-baked Amish-style beef and bell pepper casserole is the kind of practical, hearty supper that fits right into a busy weeknight while still feeling comforting enough for Sunday dinner. Using Denver steak, condensed tomato bisque soup, and a handful of pantry-friendly ingredients creates a simple bake with old-fashioned casserole appeal: tender beef, sweet peppers, and a savory tomato-rich sauce that comes together right in the dish with very little hands-on work.
Serve this casserole with buttered egg noodles, mashed potatoes, or steamed rice to catch the rich tomato-beef juices. A side of green beans, glazed carrots, or a crisp lettuce salad balances the richness nicely, and warm dinner rolls make it easy to mop up every bit of sauce from the plate.
Oven Baked 5-Ingredient Amish Beef and Bell Pepper Casserole
Servings: 6
Ingredients
1 1/2 pounds beef Denver steak
1 can (10 3/4 ounces) condensed tomato bisque soup
2 bell peppers, sliced
1 medium onion, sliced
1 teaspoon salt
1/2 teaspoon black pepper
2 tablespoons water
Directions
1. Preheat the oven to 350°F and lightly grease a 9x13-inch baking dish.
2. Cut the Denver steak into serving-size pieces or thick strips, then arrange the raw beef in an even layer in the prepared baking dish. Season with the salt and black pepper.
3. Scatter the sliced bell peppers and onion evenly over the beef.
4. In a small bowl, stir the condensed tomato bisque soup with the water just until smooth, then pour it evenly over the meat and vegetables.
5. Cover the dish tightly with foil and bake for 1 hour, or until the beef is tender and the peppers are soft. Remove the foil for the last 10 minutes if you would like the sauce to thicken slightly.
6. Let the casserole rest for 5 to 10 minutes before serving, then spoon the beef, peppers, and sauce onto plates.
Variations & Tips
Use Different Peppers: A mix of red, green, and yellow bell peppers gives the casserole a sweeter, more colorful finish. Green peppers taste a bit sharper, while red and yellow peppers become especially mellow and rich after baking.
Make It More Filling: Add sliced mushrooms or a layer of thinly sliced potatoes under the beef if you want to stretch the casserole further. If using potatoes, cut them thinly so they cook through in the same baking time.
Choose the Right Cut: Denver steak has good marbling and bakes up flavorful, but you can also use chuck steak or round steak if that is what you have. If substituting a leaner cut, check for tenderness and add a few extra tablespoons of water if the dish looks dry.
Seasoning Tip: Since condensed soup already contains salt, taste the finished sauce before adding any extra seasoning at the table. A light pinch of garlic powder or paprika can be added before baking if you want a slightly deeper savory flavor without changing the character of the dish.
Make-Ahead Tip: You can assemble the casserole several hours ahead, cover it, and refrigerate it until ready to bake. Let the dish sit at room temperature for about 20 minutes before it goes into the oven so it bakes more evenly.
