Ingredients & Their Essential Roles
- 6 medium Yukon Gold or Russet potatoes – The foundation of the dish. Yukon Golds offer a naturally buttery texture, while Russets create ultra-soft, tender layers.
- 1 medium onion, thinly sliced – Adds subtle sweetness and depth that balances the richness of the cheese.
- 3 tablespoons butter – Provides richness and forms the base of the roux for a silky smooth sauce.
- 3 tablespoons all-purpose flour – Thickens the sauce, ensuring a creamy consistency that clings beautifully to the potatoes.
- 2 cups whole or 2% milk – Creates the creamy body of the sauce; whole milk offers the richest result.
- 2 cups shredded sharp cheddar cheese – The star ingredient, delivering bold, tangy cheesiness.
- 1/2 cup grated Parmesan cheese – Adds nutty complexity and enhances the savory profile.
- 2 cloves garlic, minced – Infuses aromatic warmth and depth.
- 1 teaspoon salt – Essential for bringing out all the flavors.
- 1/2 teaspoon black pepper – Adds subtle heat and balance.
- Optional: fresh thyme or parsley – For a fresh, herbaceous finish.
Step-by-Step Instructions
- Prepare the potatoes: Peel and thinly slice the potatoes to about 1/8-inch thickness. Uniform slices ensure even cooking and a perfect texture.
- Layer the slow cooker: Lightly grease the inside of your slow cooker. Add a layer of sliced potatoes, followed by a small portion of onions.
- Create the cheese sauce: In a saucepan over medium heat, melt the butter. Whisk in the flour and cook for 1 minute until lightly golden. Slowly whisk in the milk, stirring constantly until thickened.
- Add flavor: Stir in garlic, salt, pepper, cheddar cheese, and Parmesan until fully melted and smooth.
- Assemble: Pour a portion of the cheese sauce over the potatoes. Repeat layers until all ingredients are used, finishing with sauce on top.
- Slow cook: Cover and cook on LOW for 5–6 hours or HIGH for 3–4 hours, until the potatoes are fork-tender.
- Rest and serve: Let the dish rest for 10–15 minutes before serving to allow the sauce to set.
