Ingredients for High Protein French Onion Gnocchi

Here’s what you’ll need to make this delicious High Protein French Onion Gnocchi:

1 pound potato gnocchi – Use traditional or protein-enriched gnocchi for an extra punch in nutrition and flavor.
2 tablespoons butter – Unsalted butter adds richness and a velvety finish to our onions.
3 large yellow onions – Sweet and flavorful when caramelized, these are the stars of the show.
1 teaspoon salt – Essential for enhancing flavors as we build our dish.
1/2 teaspoon black pepper – Just the right kick to round out the savory experience.
2 cloves garlic – Minced garlic brings aromatic depth that elevates our dish.
2 tablespoons all-purpose flour – A thickener for our sauce, ensuring creaminess in every bite.
2 cups beef broth – Low-sodium preferred, our broth serves as the soulful base for this recipe.
1/2 cup dry white wine – Optional but highly recommended; it adds an elegant touch to the flavor profile. Substitute with additional broth as needed.
1 teaspoon fresh thyme leaves – Fresh herbs are the finishing touch; they brighten our dish beautifully.
1/2 cup plain Greek yogurt – Full-fat yogurt adds creaminess and a healthy twist to the traditional Alfredo approach.
1 1/2 cups shredded Gruyère cheese – This rich, nutty cheese really makes the dish sing—use 1 cup for mixing and 1/2 cup for topping.
3/4 cup grated Parmesan cheese – It brings a salty, savory dimension to each serving.
2 cups cooked, shredded chicken breast – Rotisserie chicken works wonders here, making preparation a breeze.
Fresh parsley – A sprinkle for garnish, bringing color and flavor freshness to the table.

How to Make High Protein French Onion Gnocchi

Follow these simple steps to prepare this delicious High Protein French Onion Gnocchi:

Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C) and lightly grease a 2-quart baking dish to prevent any sticky situations down the road.

Step 2: Cook the Gnocchi
Prepare the gnocchi according to the package directions, usually about 2-3 minutes until they rise to the surface of boiling water. Drain well and set aside.

Step 3: Caramelize the Onions
In a large skillet over medium heat, melt the unsalted butter. Add the thinly sliced onions and sprinkle with salt. The magic happens here — cook the onions for about 25-30 minutes, stirring every 5 minutes until they turn a deep golden brown and smell absolutely divine.

Step 4: Add Flavors
Once your onions are beautifully caramelized, add in the minced garlic and let it cook for a fragrant minute. Next, sprinkle the flour over the onions and stir until well combined. Give it a minute to cook, allowing the flour to lose its raw flavor.

Step 5: Create the Sauce
Gradually whisk in the beef broth and the white wine, if using. Bring this heavenly mixture to a simmer and cook until it thickens, about 3-5 minutes.

Step 6: Combine Everything
Remove the skillet from heat and let it cool for a couple of minutes. Stir in the thyme, Greek yogurt, cooked gnocchi, shredded chicken, and 1 cup of the Gruyère cheese, blending everything into a cheesy, creamy hug of flavor.

Now, transfer this delicious mixture into your prepared baking dish. Top with the remaining 1/2 cup of Gruyère and all the Parmesan cheese for that irresistible golden crust.

To finish, pop your baking dish into the oven and bake for 20-25 minutes, until it’s bubbling and beautifully golden on top.

Once out of the oven, let it rest for 5 minutes to allow all those incredible flavors to meld together perfectly. Finally, garnish with fresh parsley before you dig in.

This High Protein French Onion Gnocchi is not just a meal; it’s an experience. Serve it up with some crusty bread or a simple salad, and you’re in for a delightful evening. Enjoy every cheesy, savory bite!
