Ingredients

Scale

Main Ingredients

  • 1½ tablespoons olive oil
  • 2½ tablespoons salted butter
  • Kosher salt, to taste
  • Freshly cracked black pepper, to taste
  • 24 ounces store-bought gnocchi
  • 2 pounds yellow onion, halved and thinly sliced
  • 1½ tablespoons thyme, finely chopped
  • 6 cloves garlic, minced
  • ½ cup dry white wine (Sauvignon Blanc recommended)
  • 2½ teaspoons dijon mustard
  • 2½ tablespoons all-purpose flour
  • 1 teaspoon Worcestershire sauce
  • 1 large bay leaf
  • 2½ cups low sodium beef stock
  • 1½ cups gruyère cheese, freshly grated
  • ½ cup parmesan cheese, freshly grated


Instructions

  1. Caramelize the Onions: Heat olive oil and butter over medium heat until butter melts. Add the thinly sliced onions and stir every few minutes. Slowly caramelize the onions for 45-60 minutes, ensuring they brown gradually without burning. If the onions dry out, add 1½ teaspoons of water at a time and stir.
  2. Prepare the Gnocchi Water: About 40 minutes into caramelizing, bring a medium pot of salted water to a boil to cook the gnocchi later.
  3. Add Herbs and Garlic: Once the onions turn deep brown, stir in finely chopped thyme and minced garlic. Cook for 2 minutes until fragrant.
  4. Deglaze with Wine: Pour in the dry white wine and cook until it reduces by about half, approximately 3-4 minutes.
  5. Thicken the Sauce: Stir in all-purpose flour and cook for 1-2 minutes until the mixture slightly thickens. Add dijon mustard and Worcestershire sauce, stirring until well combined with the onion mixture.
  6. Add Stock and Simmer: Pour in the low sodium beef stock and add the bay leaf. Scrape the browned bits from the skillet bottom. Bring to a boil, then reduce to a simmer and cook until the liquid slightly reduces, about 6-7 minutes. Season with kosher salt and freshly cracked black pepper to taste.
  7. Cook the Gnocchi: While the sauce simmers, add the gnocchi to the boiling salted water. Once the gnocchi float to the top, drain them well.
  8. Combine Gnocchi and Sauce: Transfer the drained gnocchi to the onion sauce and stir gently to combine.
  9. Add Cheese and Broil: Sprinkle grated parmesan cheese over the gnocchi, then top with grated gruyère. Place in the oven and broil for 3-5 minutes, or until the cheese is melted and bubbly.
  10. Garnish and Serve: Garnish with additional thyme. Serve immediately with crusty bread, mashed potatoes, or a fresh salad. Enjoy your comforting French Onion Gnocchi!

Notes

  • Caramelizing onions is a slow process; patience is key for the best flavor.
  • If the pan gets too dry during caramelization, add small amounts of water to prevent burning.
  • Use freshly grated cheeses for optimal melting and flavor.
  • Adjust seasoning after sauce reduction for balanced taste.
  • This dish pairs well with crusty bread or a light green salad.
