Why You’ll Love Caramelized Onion and Gnocchi Bake with Gruyère Cheese
A Perfect Balance of Flavors and Textures
One of the best things about this dish is the amazing balance it strikes between crispy, tender, and gooey. The gnocchi is first crisped up in olive oil, giving it a crunchy, golden exterior, while the inside remains soft and pillowy. The caramelized onions, on the other hand, add a rich, sweet depth to the dish, their long, slow cooking transforming them into tender, golden morsels that melt in your mouth. And, of course, the Gruyère cheese brings its signature nutty, creamy flavor that adds an extra layer of indulgence.
The balsamic or sherry vinegar, added at the end, creates a perfect contrast, adding just a touch of acidity to balance the richness of the butter and cheese. Together, these elements create a dish that’s hearty, comforting, and incredibly flavorful.
Ideal for Cozy Nights or Family Gatherings
This recipe is versatile enough for both casual weeknight dinners and special gatherings. You can enjoy it on a quiet evening after a busy day or serve it as part of a larger meal when you have guests over.

How to Make Caramelized Onion and Gnocchi Bake with Gruyère Cheese
Now that you have everything ready, let’s dive into the step-by-step instructions. This recipe may look long, but don’t be intimidated — it’s a straightforward process with some easy-to-follow steps that guarantee a delicious result.
Step 1 – Prepare the Ingredients
Start by halving and thinly slicing the yellow onions. You should end up with about 7 cups of sliced onions. Set them aside for later. Next, strip the leaves from the thyme sprigs until you have about 2 tablespoons of fresh thyme leaves. Prepare your gnocchi by opening the packages — no need to thaw them, as they’ll crisp up better if cooked straight from the package.
Step 2 – Crisp the Gnocchi
Heat 1 tablespoon of olive oil in a large, heavy-bottomed skillet over medium heat. Once the oil is hot, add half of the gnocchi in a single layer. Let them cook undisturbed for 3-5 minutes, or until the bottoms are golden brown and crispy. This step is essential for getting that delightful crunch. Once golden, transfer the gnocchi to a baking sheet in a single layer. Repeat the process with the remaining gnocchi and olive oil.
Step 3 – Caramelize the Onions
Now it’s time to caramelize the onions. In the same skillet, melt 2 tablespoons of unsalted butter over medium heat. Add the sliced onions, half of the thyme leaves, and season with kosher salt and freshly ground black pepper. Stir the onions occasionally and keep the heat medium to avoid burning. Caramelizing the onions takes about 28-30 minutes, and you want them to turn a deep golden brown and become very soft. The slow cooking will unlock the onions’ natural sweetness, making them a perfect complement to the gnocchi and cheese.

Step 4 – Add Vinegar and Combine
Once the onions are caramelized, it’s time to add the vinegar. Pour the balsamic or sherry vinegar over the onions and use a wooden spoon to scrape up any browned bits from the bottom of the pan. Stir for about 1 minute, allowing the vinegar to evaporate. This step adds a touch of acidity to balance out the richness of the dish. Remove the pan from the heat.
Step 5 – Broil with Gruyère Cheese
Return the crispy gnocchi to the skillet and gently stir to combine with the onions. Taste and adjust the seasoning with more salt if needed. Spread the gnocchi and onion mixture into an even layer and sprinkle the grated Gruyère cheese evenly over the top. Preheat your oven’s broiler and position the oven rack about 6-8 inches from the heating element. Place the skillet in the oven and broil for 4-6 minutes, or until the cheese is melted, bubbly, and golden brown. Keep an eye on it to ensure the cheese doesn’t burn.
Step 6 – Garnish and Serve
Once the cheese has melted and turned golden, remove the skillet from the oven. Garnish the dish with the remaining thyme leaves and a few grinds of black pepper. Serve hot and enjoy the perfect combination of crispy gnocchi, sweet caramelized onions, and creamy, melted Gruyère cheese.
Tips for Perfecting Your Caramelized Onion and Gnocchi Bake
Patience is Key for Caramelized Onions
When caramelizing onions, patience is your best friend. It’s tempting to turn up the heat to speed up the process, but doing so can cause the onions to burn before they fully caramelize. Stick with medium heat and give the onions enough time to develop their natural sweetness. The slow, patient cooking process is what brings out their deep, rich flavor.
Don’t Overcrowd the Gnocchi
For the best crispy texture, avoid overcrowding the pan when cooking the gnocchi. Cook them in batches to ensure they have enough space to crisp up properly. If you crowd them in the pan, they’ll steam rather than crisp, and you won’t get that satisfying golden brown exterior.
Experiment with Cheese
While Gruyère is the star of this dish, feel free to experiment with other cheeses. Fontina, Swiss, or even mozzarella can be used in place of Gruyère, though each will change the flavor profile slightly. If you prefer a more intense flavor, Parmesan could also be a good choice for a topping.
Adjust Seasoning to Taste
Always taste your dish before it goes into the oven. The seasoning can make a big difference in bringing out the flavors of the gnocchi, onions, and cheese. If you like your dishes more flavorful, don’t hesitate to add a little more salt or pepper.

Frequently Asked Questions (FAQs)
Can I Make This Recipe Ahead of Time?
Yes, you can. To save time, you can prepare the caramelized onions and crisp the gnocchi in advance. Store both in the refrigerator, and when you’re ready to serve, simply combine them, add the cheese, and broil. This makes it perfect for meal prep or if you want to cut down on cooking time.
What Can I Substitute for Gnocchi?
If gnocchi isn’t available, you can substitute it with other types of pasta, such as small ravioli, cavatelli, or even homemade potato dumplings. Roasted or boiled potatoes also work as a suitable replacement for gnocchi.
Can I Use a Different Type of Cheese?
While Gruyère is the ideal cheese for this recipe, you can experiment with other cheeses like Fontina, Swiss, or even sharp cheddar. Each type of cheese will lend a different flavor to the dish, so feel free to choose based on your preferences.
How Do I Store Leftovers?
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, place the dish in the oven at a low temperature until warmed through, or use the microwave for a quicker option. Note that the gnocchi may lose some of its crispness when reheated.

Can I Make This Recipe Vegetarian?
Yes, this recipe is already vegetarian. However, you can make it vegan by using plant-based butter and cheese alternatives. Vegan mozzarella or cashew-based cheeses are good options for keeping the creamy texture intact.
