2 cloves garlic – Fresh garlic gives a fragrant twist that sings in harmony with the onions.

2 tablespoons all-purpose flour – Helps to thicken the sauce, giving it that dreamy, luscious quality.

2 cups beef broth – Provides a robust backbone to the dish, infusing each bite with rich, meaty goodness.

1/2 cup dry white wine – A splash of wine lifts the flavors and adds a complexity that’s out of this world.

1 teaspoon fresh thyme leaves – Adds a fragrant herbaceous note that enhances the overall flavor profile.

1/2 cup plain Greek yogurt – Adds a surprising creamy tang while boosting the protein content of the dish.

1 1/2 cups shredded Gruyère cheese – Because what’s French onion without cheese? Melty, rich, and slightly nutty, it takes the dish over the top.

3/4 cup grated Parmesan cheese – For that perfect, salty, umami punch on top.

Fresh parsley – To garnish, adding a pop of color and freshness to each serving.

How to Make High Protein French Onion Gnocchi

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

Step 1: Preheat the oven
Set your oven to 375°F (190°C). Lightly grease a 2-quart baking dish to prevent any sticking and ensure easy serving later.

Step 2: Cook the gnocchi
Cook the gnocchi according to package instructions until they float to the top of the boiling water, typically 2-3 minutes. Drain well, and set aside with a mysterious wink as they await their transformation.

Step 3: Sauté the onions
In a large skillet, melt the butter over medium heat. Add the sliced onions and salt. Cook for a soul-warming 25-30 minutes, stirring every 5 minutes, until the onions are beautifully caramelized to a deep golden color. Your kitchen will start to smell divine!

Step 4: Add garlic and create the sauce
Add minced garlic to the skillet, and let it cook for about 1 minute until fragrant. Sprinkle the flour over the cooked onions and stir to combine, cooking for another minute to develop that base flavor. Slowly whisk in the beef broth and white wine, stirring until the mixture thickens, about 3-5 minutes.

Step 5: Stir in the delicious additions
Remove the skillet from the heat and allow it to cool for just a few moments. Stir in the thyme, Greek yogurt, cooked gnocchi, shredded chicken, and 1 cup of the Gruyère cheese, making sure everything is evenly coated and ready for baking.

Step 6: Bake to perfection
Transfer the mixture into your prepared baking dish, spreading it out evenly. Top with the remaining 1/2 cup of Gruyère cheese and all of the Parmesan cheese. Bake until golden and bubbly, about 20-25 minutes.

Let it rest for about 5 minutes before diving in, garnished with freshly chopped parsley. Serve this beauty in bowls, draw your loved ones near, and prepare to bask in the glow of everyone’s blissful expressions as they savor every bite of your amazing High Protein French Onion Gnocchi. Enjoy!
