Ingredients

For the Creamy Sauce Base

• 1 cup (240ml) heavy cream
• 1 cup (240ml) whole milk
• 2 tbsp (16g) all-purpose flour (thickens the sauce)
• 1 tsp salt
• ½ tsp black pepper, freshly ground
• ½ tsp garlic powder
• ½ tsp onion powder

For the Potato & Cheese Layers

• 1.5 kg (~3 lbs) russet or Yukon Gold potatoes, peeled and thinly sliced (~⅛ inch thick)
• 1 cup (100g) shredded sharp cheddar cheese
• ½ cup (50g) grated Parmesan cheese

For the Finishing Touch

• 1 tbsp (14g) unsalted butter, cut into small pieces
• ¼ tsp paprika (adds color and subtle smokiness)

✅ Optional Upgrades:

• ½ cup caramelized onions between layers
• Fresh thyme or rosemary sprigs tucked in before cooking
• Crispy bacon or green onions on top after cooking

Step-by-Step Instructions

1. Prep & Grease the Slow Cooker

• Lightly grease the inside of your slow cooker bowl with butter or nonstick spray—this prevents sticking and makes cleanup easier.

2. Make the Creamy Sauce

In a medium bowl:

• Whisk together heavy cream, milk, flour, salt, pepper, garlic powder, and onion powder until smooth and well blended.

3. Layer the Potatoes & Cheeses

In the greased slow cooker:

1. Add a single layer of sliced potatoes (slightly overlapping).
2. Drizzle with some of the cream mixture.
3. Sprinkle with a portion of cheddar and Parmesan.
4. Repeat layers until all ingredients are used, finishing with:
   • A final layer of cheese
   • Evenly distributed butter pieces
   • A light dusting of paprika

4. Cook Low and Slow

• Cover and cook:
  • On LOW for 6–8 hours, or
  • On HIGH for 3–4 hours
• Potatoes are done when they’re fork-tender and the sauce is thick and bubbly.

5. Rest Before Serving

• Once cooked, turn off the slow cooker and let rest 10–15 minutes with the lid on.
• This allows the sauce to settle, thicken slightly, and bind everything together.

6. Serve Warm & Creamy

• Scoop out gently with a spatula or serving spoon.
• Garnish with fresh herbs, extra cheese, or crispy bacon if desired.

Serve alongside:

• Roast turkey, ham, or chicken
• Green beans, peas, or a crisp salad
• Gravy or sour cream for extra indulgence

You Must Know

• Slice potatoes evenly —uneven cuts lead to uneven cooking.
• Use full-fat dairy —low-fat versions may curdle or thin out.
• Shred your own cheese —pre-shredded contains anti-caking agents that hinder melting.
• Tastes better the next day! Flavors deepen overnight.
• Freezer-friendly —cool completely and freeze up to 3 months.

Storage Tips

• Store leftovers in an airtight container in the fridge for up to 5 days.
• Reheat in oven at 350°F for 15–20 minutes (best texture). Microwave works but may separate.
• Freeze for up to 3 months —thaw overnight before reheating.

Ingredient Substitutions

Serving Suggestions

• Serve family-style right in the slow cooker insert.
• Great for potlucks—bring the whole unit!
• Double the batch and freeze half for future comfort.
• Pack in lunchboxes (reheat safely).

• Label your dish: People will ask for the recipe.
• Say “ready?” before serving —it’s part of the ritual.

These potatoes don’t shout. They bubble quietly in the slow cooker, creamy and inviting, saying everything a great side should: “Scoop me slow. Share me. This is good.” That’s how the best ones begin—not with silence, but with potato, patience, and someone who says, “Let’s make it together.”
