There is something wonderfully practical about a simple baked beef supper, especially one that leans on just a handful of pantry and refrigerator staples to make a hearty meal. This Amish-style beef and garlic butter casserole has that old-fashioned, no-fuss spirit so many of us grew up with in the Midwest, where a good cut of beef, a baking dish, and a few flavorful additions could come together into a supper that felt special without being complicated. Spreading jarred garlic butter over beef baseball steak and baking it with three easy ingredients makes a rich, savory dish with plenty of home-cooked comfort.
Serve this casserole with mashed potatoes, buttered egg noodles, or fluffy rice to catch every bit of the garlicky beef juices. A side of green beans, glazed carrots, corn, or a crisp garden salad balances the richness nicely, and a basket of warm dinner rolls is always welcome at the table for sopping up the buttery sauce.
Oven Baked 5-Ingredient Amish Beef and Garlic Butter Casserole
Servings: 4
Ingredients
2 beef baseball steaks, about 8 ounces each
1/2 cup store-bought jarred garlic butter spread
1 medium onion, thinly sliced
8 ounces sliced mushrooms
1 packet onion soup mix
Directions
1. Preheat your oven to 375°F and lightly grease a medium baking dish. Lay the beef baseball steaks in the dish in a single layer.
2. Spread the jarred garlic butter evenly over the tops of the steaks, covering the surface well so the butter can melt down into the meat as it bakes.
3. Scatter the sliced onion and mushrooms over and around the beef, then sprinkle the onion soup mix evenly across the top.
4. Cover the dish tightly with foil and bake for 30 minutes. Remove the foil and continue baking for 10 to 15 minutes more, or until the beef reaches your preferred doneness and the vegetables are tender.
5. Let the casserole rest for 5 to 10 minutes before serving so the juices settle. Spoon the onions, mushrooms, and buttery pan sauce over the beef when plating.
Variations & Tips
Add potatoes: If you want this to feel even more like a full casserole meal, nestle halved baby potatoes around the beef before baking. They will soak up the buttery juices beautifully, though you may need to add a little extra baking time until they are fork-tender.
Use a different mushroom: Plain white mushrooms work just fine, but cremini mushrooms bring a deeper, earthier flavor. If your family likes mushrooms, this is an easy way to make the dish taste a little heartier without adding extra fuss.
Watch the doneness: Baseball steaks are thick and juicy, which makes them lovely for baking, but oven times can vary depending on thickness. For the best result, use a meat thermometer and pull the beef when it reaches the doneness your family prefers.
Make the sauce stretch: If you would like more spoonable sauce for noodles or mashed potatoes, add a splash of beef broth to the baking dish before covering it with foil. That little bit of extra liquid blends with the garlic butter and soup mix into a savory gravy-like finish.
Let it rest: A short rest after baking is one of those old kitchen habits that truly matters. It helps the meat hold onto its juices, and it gives the onions, mushrooms, and buttery drippings a moment to settle into a richer sauce.
