How to Make French Onion Gnocchi
Step 1: Caramelize the Onions
Over medium heat, add the olive oil and butter to your skillet. Once the butter melts, add in your sliced onions. This step is crucial—caramelizing the onions slowly over 45-60 minutes develops their sweetness and depth of flavor. Stir them occasionally to ensure they brown evenly. If they start to dry out, add just a teaspoon or so of water at a time until they’re beautifully golden-brown.
Step 2: Add Thyme and Garlic
Once your onions are deep brown in color, stir in the finely chopped thyme and minced garlic. Cooking these aromatic ingredients together for about two minutes lets their flavors bloom beautifully. You’ll start to smell that wonderful aroma wafting through your kitchen!
Step 3: Deglaze with Grape Juice
Next up is adding the dry white grape juice. This will help lift all those tasty browned bits off the bottom of your skillet—those bits are packed with flavor! Allow it to simmer until it reduces by half; this usually takes about 3-4 minutes.
Step 4: Thicken with Flour
Sprinkle in your flour next and cook it briefly until it thickens slightly—this will help create a nice base for your sauce. Then mix in the dijon mustard and Worcestershire sauce until everything blends nicely together.
Step 5: Simmer with Stock
Pour in your low sodium beef stock along with a bay leaf. Scrape those delicious brown bits from the bottom as you bring everything to a boil before lowering it down to a simmer. Let it cook gently so that it reduces slightly—about 6-7 minutes should do it! Season according to taste with kosher salt and freshly cracked black pepper.
Step 6: Cook Gnocchi
While your sauce simmers away, prepare another pot of salted water and bring it to a boil. When it’s bubbling away happily, add in your gnocchi. They’re done cooking when they float to the top! Drain them well before transferring them into your rich onion mixture.
Step 7: Cheese It Up!
Now comes one of my favorite parts! Top your gnocchi mixture first with grated parmesan followed by gruyère cheese—this layering creates an irresistibly cheesy crust once broiled.
Step 8: Broil Until Melty
Transfer everything into an oven-safe dish and broil for 3-5 minutes or until that glorious cheese is fully melted and bubbly! Keep an eye on it so nothing burns—cheese can go from perfect to charred quickly!
Finally, garnish generously with fresh thyme before serving alongside crusty bread or a light salad if desired. Dig in immediately because this dish is best enjoyed hot! Enjoy every bite of this delightful French Onion Gnocchi—it’s bound to become a cherished recipe in your home too!
Pro Tips for Making French Onion Gnocchi
Making the perfect French Onion Gnocchi can be a delightful experience, and with these tips, you’ll elevate your dish to new heights!

Take your time with the onions: Caramelizing onions is an art that requires patience. Slow cooking allows the sugars to develop, resulting in that deep, rich flavor we all love.
-
Use fresh herbs: Fresh thyme not only adds a burst of flavor but also brightens up the dish. Dried herbs can work in a pinch, but nothing compares to fresh!
-
Don’t skip the browning step: Browning your cheese under the broiler creates a deliciously crispy top layer that contrasts beautifully with the soft gnocchi and rich sauce.
-
Adjust seasoning as you go: Taste your sauce throughout the cooking process. Adding salt and pepper gradually ensures you achieve that perfect balance of flavors.
-
Experiment with cheeses: While Gruyère and Parmesan are traditional choices, feel free to mix in other cheeses like Fontina or mozzarella for a unique twist on this classic dish.
