Ingredients & Their Purpose

Every ingredient in this recipe has a specific role to play. Here's what you'll need — and why it matters:

🥩 Beef Sirloin or Stew Meat (2 lbs)

The hearty protein base of this dish. Sirloin gives you a tender bite, while stew meat offers depth and richness after slow cooking.

🛢️ Olive Oil (2 tbsp)

Used for browning the beef, which adds flavor through caramelization and locks in juices before slow cooking.

🥔 Yukon Gold or Russet Potatoes (2 lbs, thinly sliced)

The foundation of the casserole. Yukon Golds are creamy and buttery, while Russets break down a bit more, adding texture.

🧅 Medium Onion (1, thinly sliced)

Adds sweetness and depth to the casserole as it cooks down and melds into the sauce.

🧄 Garlic (2 cloves, minced)

Enhances the umami and savory notes of the dish.

🥣 Beef Broth (1 cup)

The liquid base that helps tenderize the meat and carry flavor throughout the casserole.

🥄 Sour Cream (1 cup)

Adds a tangy creaminess that balances the richness of the cheese and beef.

🥫 Cream of Mushroom Soup (1 can, 10.5 oz)

A classic casserole staple, it adds silky texture and savory mushroom flavor to the sauce.

🍶 Worcestershire Sauce (1 tbsp)

A secret weapon! Adds deep, meaty umami and a subtle tang.

🌶️ Smoked Paprika (1 tsp)

Brings smoky warmth to the casserole, elevating the flavor profile.

🧂 Salt and Black Pepper (to taste)

Essential for seasoning every layer and enhancing natural flavors.

🧀 Cheddar Cheese (2½ cups, shredded)

The creamy, melty glue that ties everything together. Use sharp cheddar for bold flavor, or mix in mild for creaminess.

🌿 Fresh Parsley (optional, for garnish)

Adds a fresh finish and color contrast right before serving.

Step-by-Step Instructions

🔥 Step 1: Brown the Beef

In a large skillet over medium-high heat, heat 2 tablespoons olive oil. Add the cubed beef in batches (avoid overcrowding) and sear until browned on all sides. This step builds flavor that slow cooking alone can’t achieve. Set aside.

> Pro Tip: Don’t skip browning — it gives the meat a rich, caramelized crust that deepens the overall flavor.

🧅 Step 2: Layer the Ingredients

Grease the inside of your slow cooker with cooking spray or butter.

1. Place half of the sliced potatoes and onions on the bottom.

2. Season lightly with salt and pepper.

3. Add half of the browned beef, then sprinkle with 1 cup cheddar cheese.

4. Repeat layers with remaining potatoes, onions, beef, and another 1 cup cheddar.

🥄 Step 3: Make the Creamy Sauce

In a mixing bowl, whisk together:

1 cup beef broth

1 cup sour cream

1 can cream of mushroom soup

1 tbsp Worcestershire sauce

1 tsp smoked paprika

2 cloves minced garlic

Salt and pepper, to taste

Pour this sauce evenly over the layered ingredients in the slow cooker.

⏳ Step 4: Cook Low and Slow

Cover with the lid and cook on Low for 6–7 hours or High for 3–4 hours, until the potatoes are fork-tender and the beef is juicy and cooked through.

---

🧀 Step 5: Finish with Cheese

In the last 10 minutes of cooking, sprinkle the remaining ½ cup of cheddar cheese on top. Cover again and let it melt into a gooey, irresistible topping.

Garnish with fresh parsley if desired, and serve warm.

Pro Tips for Perfect Results

Slice potatoes evenly using a mandoline for consistent cooking.

Don’t lift the lid too often — it lets out heat and can affect cooking time.

Add a splash of heavy cream before serving for a more luxurious texture.
