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 has melted and starts to bubble, toss in the sliced onions. Stir them occasionally but don’t rush this process; good caramelized onions take about 45-60 minutes. This slow cooking allows their natural sugars to develop a sweet flavor that forms the base of our sauce. If things start to dry out too much, don’t hesitate to add a splash of water.
Step 2: Add Thyme and Garlic
Once your onions are deep brown and fragrant (around 40 minutes in), stir in the finely chopped thyme and minced garlic. Cook for about two minutes until everything is beautifully aromatic. This step really adds depth to our sauce!
Step 3: Deglaze with White Grape Juice
Pour in the white grape juice and let it simmer until reduced by half—this should take around 3-4 minutes. This helps pick up all those tasty browned bits stuck at the bottom of your pan while adding just enough acidity to brighten up the flavors.
Step 4: Thicken the Sauce
Stir in the flour next; this will help thicken your sauce just right! Cook this mixture for about 1-2 minutes before adding in the dijon mustard and worcestershire sauce—stirring well until everything is combined.
Step 5: Simmer with Beef Stock
Now it’s time to introduce our savory beef stock along with that bay leaf we’ve been saving. Scrape any brown bits from the bottom of your skillet—you want all those flavors! Bring everything to a boil then lower it down to a gentle simmer for about 6-7 minutes until slightly thickened. Season with kosher salt and freshly cracked black pepper to taste.
Step 6: Cook the Gnocchi
While you wait for your delicious sauce to thicken up nicely, bring another pot of salted water to boil and add your gnocchi. Once they float to the top (which means they’re done!), drain them well before mixing them into your lovely onion sauce.
Step 7: Top with Cheese & Broil
Sprinkle grated parmesan over your gnocchi first followed by gruyère cheese—it creates such an amazing cheesy crust! Transfer this beauty into an oven-safe dish and broil on high for about 3-5 minutes or until bubbly and golden.
Step 8: Serve & Enjoy!
Garnish with some fresh thyme leaves for that final touch. Serve immediately alongside crusty bread or mashed potatoes—trust me; you’ll want something handy to soak up all that incredible flavor! Enjoy every bite of this cozy French Onion Gnocchi!
Pro Tips for Making French Onion Gnocchi
Making this French Onion Gnocchi dish is a joy, and with a few clever tips, you can elevate your cooking experience even further!
-
Take your time with the onions: Slow-cooking the onions allows them to caramelize beautifully, enhancing their sweetness and flavor. Rushing this step can lead to burnt bits that won’t taste as delightful.
-
Use fresh herbs: Fresh thyme not only adds depth of flavor but also a pleasant aroma. Dried herbs can work in a pinch, but fresh will always make your dish shine.
-
Don’t skip the browning: When you add the gnocchi to the sauce, make sure it’s hot and bubbling. This helps to meld all the flavors together and gives the gnocchi a deliciously soft texture.
-
Experiment with cheese: If you’re feeling adventurous, try mixing different cheeses like fontina or mozzarella with the gruyère for added creaminess and flavor complexity.
-
Make it ahead: You can prepare the onion sauce in advance and just cook the gnocchi right before serving. This will save you time when entertaining guests or on busy weeknights.
