Instructions

Lightly grease the inside of the crockpot with cooking spray or oil.
In a medium saucepan over medium heat, melt the butter and cook the minced garlic for about 30 seconds until fragrant.
Whisk in the flour and cook for 1 minute to form a smooth roux.
Gradually whisk in the milk, stirring constantly until the sauce thickens (about 3–5 minutes).
Remove from heat and stir in cheddar cheese, salt, pepper, and paprika until smooth and creamy.
Layer half of the sliced potatoes in the crockpot and sprinkle with half of the chopped onions.
Pour in half of the cheese sauce over the potatoes and onions.
Repeat with the remaining potatoes, onions, and cheese sauce.
Top with grated parmesan cheese.
Cover and cook on low for 6–7 hours or on high for 3–4 hours until the potatoes are fork-tender and the sauce is bubbling.

Notes

Add chopped cooked bacon between layers for extra flavor.

Use aged gouda or gruyère for a sharper cheese profile.

Swap russets with Yukon gold potatoes for a buttery texture.

Use a 1:1 gluten-free flour blend for a gluten-free version.

Mix in fresh herbs like thyme or rosemary for added depth.

Store leftovers in the fridge for up to 4 days; reheat with a splash of milk if needed.
