Can I make this recipe vegetarian?

Absolutely! Simply omit the chicken and add more vegetables like sautéed mushrooms, bell peppers, or extra spinach. The caramelized onions provide so much flavor that you won't miss the meat. You might also consider adding some toasted walnuts or pine nuts for texture.

What if I can't find Gruyere cheese?

Gruyere gives that authentic French onion soup flavor, but Swiss cheese makes an excellent substitute. In a pinch, a combination of mozzarella and provolone will work too, though the flavor profile will be slightly different. The key is finding a good melting cheese that complements the sweet onions.

How do I prevent my lasagna noodles from sticking together after cooking?

After cooking the noodles to al dente, drain them and immediately lay them flat on parchment paper. You can also lightly drizzle them with olive oil and gently separate them with your fingers. Don't stack them on top of each other or they'll likely stick and tear.

Can I prepare components of this dish ahead of time?

Definitely! The caramelized onions can be made 1-2 days ahead and refrigerated. The sauce can be made a day ahead and gently reheated before using. You can even assemble the entire dish, cover it tightly, and refrigerate for up to 24 hours before baking - just add about 10 minutes to the baking time.

Instructions

Prepare the baking dish: Spray a 9×13-inch baking dish with nonstick spray. Set aside.
Caramelize the onions: To a large skillet over medium heat, add oil and butter. After the butter has melted, add onions and saute for 30 minutes, stirring occasionally, until very tender and golden brown. Add salt and pepper. Stir to combine. Remove from heat and set aside.
Preheat the oven: Preheat the oven to 350°F.
Prepare the sauce: Wipe out the skillet, and then to the same skillet over medium heat, add butter. Heat until melted. Add garlic, salt, pepper, crushed red pepper, and heavy cream. Stirring occasionally, heat over medium-high heat until it comes to a slow rolling boil. Reduce heat and boil gently until the sauce thickens (about 8 minutes). Remove from heat and stir in 1 cup of parmesan cheese. Set aside.
Prepare the noodles: Line a work surface with parchment paper and place the cooked lasagna noodles on it.
Make the filling: In a large bowl, mix ricotta, chicken, 1 cup of Gruyere cheese, and ½ cup of parmesan cheese until combined. Divide the filling evenly among the noodles (about ⅓ cup per noodle), spreading it out.
Add spinach and onions: Top each noodle with about 2 tablespoons spinach and an equal portion of caramelized onions.
Roll the noodles: Starting at one end, roll each noodle tightly around the filling. Place the rolls seam side down in the prepared baking dish.
Assemble and bake: Pour the sauce over the noodles, covering them completely. Top with the remaining 1 cup of Gruyere cheese. Bake for 30-35 minutes, or until cheese is melted and bubbly.
Serve: Garnish with parsley and serve warm.

Notes

Be patient while caramelizing the onions; the process takes time but is essential for the rich flavor.
You can prepare the caramelized onions and the sauce in advance to save time on the day of cooking.
Feel free to substitute Gruyere with Swiss or mozzarella cheese if desired.
For a vegetarian version, skip the chicken and add more spinach or mushrooms.
