🛒 The 3-Ingredient "Supper Hero" List

To reach maximum flavor with only three items, quality and fat content are your best friends.

• 1.5 lbs Ground Beef: (Recommend 80/20 or 85/15 for juicy results that stand up to baking).

• 1 Can (10.5 oz) Condensed Cream of Mushroom Soup: The "all-in-one" sauce that provides creaminess, seasoning, and umami.

• 1 Packet Dry Onion Soup Mix: The secret weapon that adds deep, savory aromatics and a "slow-cooked" taste in minutes.

👩‍🍳 Step-by-Step Instructions for the Perfect Bake

1. The Raw Patty Prep

Preheat your oven to 375°F. Divide your raw ground beef into 4 to 6 thick, even patties. Place them directly into a 9x13-inch glass baking dish. Pro Tip: Don't press them too thin; keeping them thick ensures they remain succulent during the smothering process.

2. The Smothering Sequence

In a small bowl, whisk together the condensed cream of mushroom soup and the dry onion soup mix. If you prefer a thinner gravy, add 1/4 cup of water or beef broth. Pour this mixture evenly over the raw beef patties, ensuring each one is fully "enveloped" in the mushroom blanket.

3. The Hearty Bake

Cover the dish tightly with aluminum foil to trap the moisture. Bake for 30–35 minutes. For a "golden" finish, remove the foil for the last 5 minutes of cooking. This allows the mushroom gravy to bubble and thicken around the seared edges of the beef.

4. The Rest & Serve

Let the dish sit for 5 minutes after removing it from the oven. This allows the juices to redistribute and the gravy to set. Serve over mashed potatoes, egg noodles, or steamed rice for the ultimate comfort experience.
