How to Make French Onion Melting Potatoes

3. Add remaining butter and onions to the skillet; cook over medium-low heat for 18–22 minutes until deep golden.
4. Stir in thyme, broth, and optional Worcestershire; nestle the potatoes into the onion mixture in one layer.
5. Roast uncovered 20–25 minutes until potatoes are fork-tender and broth is mostly absorbed.
6. Sprinkle with Gruyère and broil briefly, watching closely, until melted and lightly browned.

Tips for the Best French Onion Melting Potatoes

• Cut even, thick rounds for creamy centers.
• Give onions time to caramelize rather than rushing over high heat.
• Use an oven-safe skillet and keep an eye on the broiler.

Variations to Try

• Swap Gruyère for Swiss cheese.
• Add sliced mushrooms alongside the onions.
• Use beef broth for a richer classic French onion profile.

How to Store It

Cool promptly and refrigerate covered for up to 4 days. Reheat in a 375°F oven until hot, adding a spoonful of broth if dry.
