Ingredients

• 2 pounds beef chuck steak, cut into serving-size pieces
• 1 can (10.5 ounces) condensed cream of mushroom soup
• 1 large yellow onion, thinly sliced
• 1½ cups shredded mozzarella cheese

This recipe uses exactly 4 main ingredients. Black pepper, garlic powder, or cooking spray may be added optionally but are not counted.

How to Make Oven Baked Beef Kensington

1. Prepare the Beef

Preheat your oven to 350°F (175°C).

Pat the beef dry with paper towels and arrange the pieces in a lightly greased 9-by-13-inch baking dish.

For thicker pieces of chuck steak, gently pound them to an even thickness to encourage more consistent cooking.

2. Add the Onion

Scatter the sliced onion evenly over the beef.

As the dish bakes, the onion will soften and release its savory flavor into the sauce.

3. Add the Mushroom Sauce

Spoon the condensed cream of mushroom soup over the beef and onions.

Spread it into an even layer. The moisture released during baking will loosen the soup into a rich sauce.

4. Cover and Bake

Cover the baking dish tightly with aluminum foil.

Bake for approximately 1½–2 hours, or until the beef is tender.

Chuck steak contains connective tissue, so don’t rely solely on the clock. If the beef is still firm, cover it again and continue baking until it becomes tender.

5. Add the Mozzarella

Remove the foil once the beef is tender.

Sprinkle the shredded mozzarella evenly over the top.

Return the dish to the oven uncovered and bake for another 10–15 minutes, until the cheese is melted and lightly bubbling.

For a more golden top, broil for 1–2 minutes while watching closely.

6. Rest and Serve

Let the finished dish rest for 5–10 minutes before serving.

Spoon the creamy onion sauce over each portion and serve warm.

Tips for the Best Beef Kensington

• Choose chuck steak for its rich flavor and suitability for slow, moist cooking.
• Keep the dish covered during the main baking period to prevent the beef from drying out.
• Give the beef enough time to become tender. Chuck can require additional cooking beyond the estimated time.
• Add the cheese at the end so it melts smoothly without becoming tough.
• Let the casserole rest briefly before serving so the sauce can settle.

Easy Variations

If you’re not keeping the recipe strictly four ingredients, season the beef with black pepper, garlic powder, onion powder, or dried thyme.

Mozzarella can also be replaced with cheddar, Swiss, or Monterey Jack for a different flavor.

For extra vegetables, sliced mushrooms, bell peppers, or carrots can be added, although these would change the four-ingredient count.

What to Serve With Beef Kensington

Serve this creamy beef over mashed potatoes for a classic comfort-food dinner.

Egg noodles, rice, roasted potatoes, or buttered pasta are also excellent choices. Add steamed green beans, broccoli, or a simple salad for freshness.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3–4 days.

Reheat gently in a covered baking dish or saucepan until thoroughly warmed. If the sauce becomes too thick, stir in a small splash of beef broth or water.

Frequently Asked Questions

What type of beef should I use?

Chuck steak is ideal because its connective tissue breaks down during slow, moist cooking, producing a tender result.

Can I use another cut?

Yes. Stew meat or another braising-friendly beef cut can work, but cooking time may vary depending on the size and thickness of the pieces.

Why is my beef still tough?

If chuck steak is tough, it usually needs more time rather than less. Keep it covered and continue baking until the connective tissue has softened and the beef is tender.

Can I prepare this ahead of time?

Yes. Assemble the beef, onions, and mushroom soup in the baking dish, cover, and refrigerate. When ready to cook, allow additional time if starting directly from the refrigerator.
