Ingredients (Serves 6)

• 3 lbs Yukon Gold potatoes, thinly sliced
• 2 packets dry French onion soup mix
• 1/2 cup unsalted butter, melted
• 2 cups shredded Gruyère cheese, divided

How to Make Slow Cooker French Onion Potatoes

1. Prepare the slow cooker
   Lightly grease your slow cooker to prevent sticking and make cleanup easier.
2. Slice the potatoes
   Wash and slice potatoes into thin rounds (about 1/8–1/4 inch). Keep skins on for extra texture and nutrients.
3. Make the onion butter sauce
   In a bowl, mix the French onion soup mix with melted butter until fully combined. This creates a rich, savory sauce.
4. Layer the ingredients
   • Add a layer of sliced potatoes
   • Drizzle onion butter mixture
   • Sprinkle some Gruyère cheese
     Repeat layers until all ingredients are used, reserving cheese for the top.
5. Top with cheese
   Finish with the remaining Gruyère for that melty, golden crust.
6. Slow cook to perfection
   • LOW: 5–6 hours
   • HIGH: 2.5–3 hours
     Cook until potatoes are fork-tender and cheese is bubbly.
7. Optional broil for crispy top
   For a true steakhouse-style finish, broil for 3–5 minutes until golden and slightly crispy.
8. Rest and serve
   Let sit for 10 minutes before serving so the sauce thickens.
