How to Make Slow Cooker Steak and Cheddar Casserole
Prep Ingredients: Begin by washing, peeling, and slicing the Yukon gold potatoes as thinly as possible for even cooking. Aim for about 1/8-inch thickness to ensure they become tender while the dish cooks.
Sear Steak: Heat a skillet over medium-high heat and add diced sirloin steak. Sear for about 3-4 minutes on each side until nicely browned, but don t cook it through; tender texture is key!
Saut Onions and Garlic: In the same skillet, toss in chopped onions and minced garlic. Saut for roughly 5 minutes until they turn fragrant and slightly golden, enhancing the dish s flavor profile.
Layer in Slow Cooker: Start layering! Place half the sliced potatoes at the bottom of your slow cooker. Top with half the steak mixture, and then sprinkle with half of the cheddar cheese. Repeat with the remaining ingredients.
Add Liquids & Seasonings: Carefully pour low-sodium beef broth over the layered ingredients. Add dollops of sour cream, and sprinkle generously with salt, pepper, and dried thyme to bring it all together.
Slow Cook: Cover the slow cooker with the lid and cook on low for 6-8 hours or on high for 3-4 hours. The goal is to have tender potatoes and fork-tender steak, creating that irresistible creamy comfort food.
Optional: For a touch of freshness, garnish with chopped parsley before serving.
