Toss raw beef chuck eye steaks in the glass casserole dish and 4 other simple items to get a meal so delicious your husband will be begging for more!

This 5-ingredient oven beef is my kind of weeknight win: you literally toss raw beef chuck eye steaks into a glass casserole dish, add four pantry-friendly extras, and let the oven do the heavy lifting. Chuck eye is sometimes called the “poor man’s ribeye,” so you get big flavor without the big price tag. Everything bakes together in one dish, which means less cleanup and more time to catch your breath after work—plus the kind of cozy, beefy dinner that has everyone asking for seconds.

Serve these tender baked chuck eye steaks with buttery mashed potatoes or roasted baby potatoes to soak up the pan juices. A simple green side—like steamed green beans, a quick salad kit, or roasted broccoli—keeps it balanced. Warm dinner rolls or garlic bread are great for mopping up the savory juices in the bottom of the glass dish. If you’re planning ahead for lunches, pack leftover steak slices over rice or egg noodles with some of the onions and juices spooned on top.

Servings: 4

2 pounds beef chuck eye steaks (about 2–3 steaks, 1 to 1 1/2 inches thick)

Preheat your oven to 325°F (165°C). Lightly grease a 9x13-inch glass casserole dish with a bit of the olive oil or nonstick spray to keep the steaks from sticking.

Lay the raw beef chuck eye steaks flat in the bottom of the glass casserole dish in a single layer, overlapping just slightly if needed. This is your base—no pre-searing or extra pans required.

Drizzle the remaining olive oil evenly over the top of the steaks. Use clean hands or tongs to gently turn and toss the steaks right in the glass dish so they’re lightly coated in oil on all sides.

Sprinkle the dry onion soup mix evenly over the oiled steaks. Toss again briefly in the dish to coat the meat with the seasoning, then spread the steaks back into a mostly single layer.

Scatter the sliced onions over and around the steaks, tucking some slices down along the sides of the meat so they can soften and caramelize in the juices as they bake.

In a small bowl, stir the condensed cream of mushroom soup just to loosen it slightly (no extra water or milk needed). Spoon the soup over the steaks and onions, spreading it into a rough layer so most of the meat is covered. It will thin out into a savory gravy as it bakes.

Cover the glass casserole dish tightly with foil to trap steam and keep the steaks moist. Place the covered dish on the middle rack of the preheated oven.

Bake for 1 hour 30 minutes to 2 hours, or until the chuck eye steaks are very tender when pierced with a fork and the onions are soft. If your steaks are thinner, start checking around 1 hour 15 minutes; thicker steaks may need closer to 2 hours.

Carefully remove the foil, watching out for hot steam. If you’d like a bit more color on top, leave the dish uncovered and bake for an additional 10–15 minutes.

Let the casserole rest for about 5–10 minutes before serving so the juices settle slightly. Spoon the steaks onto plates and ladle the onion-mushroom gravy from the bottom of the glass dish over the top.

You can easily tweak this 5-ingredient oven beef to match what you have on hand or your family’s tastes. For extra richness, replace some or all of the olive oil with melted butter, or add a splash (2–3 tablespoons) of beef broth or red wine to the dish before baking for a deeper gravy. If you’re not a fan of mushroom soup, cream of celery or cream of onion soup will still give you a creamy sauce. Add sliced mushrooms or carrot coins on top of the steaks with the onions for more veggies without dirtying another pan. For a slightly lighter version, trim visible fat from the chuck eye steaks and use a reduced-sodium onion soup mix and low-sodium condensed soup. If your family likes a bit of heat, sprinkle in a pinch of crushed red pepper flakes with the onion soup mix. Leftovers reheat well: slice the cooked steak against the grain and warm gently in the microwave with some of the pan juices, or pile onto toasted rolls with melted cheese for an easy sandwich. For food safety, keep the raw beef refrigerated until you’re ready to assemble the casserole, and wash your hands, cutting boards, and any utensils that touch the raw meat before using them for anything else. Bake the dish until the beef reaches at least 145°F for medium and the juices run mostly clear, and refrigerate leftovers within 2 hours in shallow containers. Reheat leftovers to 165°F and enjoy within 3–4 days.
