French Onion Chicken Lasagna Roll Ups

Introduction

These French Onion Chicken Lasagna Roll Ups combine everything I love about a cozy baked pasta dinner: tender chicken, sweet caramelized onions, creamy white sauce, and plenty of melty cheese tucked inside soft lasagna noodles. They’re rich and comforting without feeling like an ordinary lasagna.

If you’ve ever wondered what are lasagna roll ups, they’re simply lasagna noodles filled with a savory mixture, rolled into little spirals, and baked together with sauce and cheese. In this version, the classic idea gets a French onion twist, with golden onions and tender chicken layered into every bite.

The best part is that you don’t need to make a complicated French onion lasagna recipe from scratch. The caramelized onions do most of the flavor work, while a simple creamy sauce brings everything together. It’s the kind of dinner that makes the kitchen smell amazing before it even reaches the table.

Ingredient Notes & Substitutions

LASAGNA NOODLES You’ll need about 12 lasagna noodles, preferably regular oven-boil noodles rather than no-boil sheets. Look for wide, sturdy noodles without cracks. Cook them just until tender because slightly firm noodles are much easier to roll. If a few tear, don’t worry; you can patch them with another piece of noodle.

CHICKEN About 2 cups of cooked, shredded chicken works beautifully here. Boneless, skinless chicken breasts are lean and easy to shred, while chicken thighs give the filling a juicier, richer texture. Leftover roasted chicken or rotisserie chicken is also a great shortcut.

YELLOW ONIONS Use about 3 large yellow onions. They’re ideal because they become sweet and deeply golden as they cook. Choose firm onions with dry, papery skins. White onions can work in a pinch, but yellow onions give these French onion lasagna roll ups their best flavor.

BUTTER & OLIVE OIL A couple of tablespoons of butter plus a little olive oil help the onions cook evenly without burning. The butter adds richness, while the oil gives you a little more room to cook the onions slowly.

GARLIC Two or three fresh garlic cloves add a gentle savory note to the onion chicken filling. Fresh garlic is best here, but about ¾ teaspoon of garlic powder can be used if that’s what you have.

CHICKEN BROTH About ½ cup of chicken broth helps loosen the caramelized onions and adds another layer of savory flavor. Low-sodium broth is a good choice because the cheese and seasonings already bring plenty of salt.

THYME About 1 teaspoon of fresh thyme leaves or ½ teaspoon dried thyme gives the dish that unmistakable French onion character. Fresh thyme is especially lovely if you have it.

ALL-PURPOSE FLOUR You’ll need roughly 3 tablespoons to thicken the creamy sauce. If you prefer, a gluten-free all-purpose flour blend can usually be substituted.

MILK About 2 cups of whole milk makes a smooth, creamy white sauce. You can use 2% milk, although the sauce won’t be quite as rich. Avoid very watery plant milks unless they’re specifically designed for cooking.

PARMESAN CHEESE Around ½ cup freshly grated Parmesan adds salty, nutty flavor to the sauce. Grating it yourself helps it melt more smoothly than pre-shredded cheese.

MOZZARELLA CHEESE About 1½ cups shredded mozzarella gives the roll ups that stretchy, golden topping everyone looks forward to. Low-moisture whole-milk mozzarella melts particularly well.

SWISS OR GRUYÈRE CHEESE About ½ cup shredded Gruyère or Swiss cheese gives the dish a classic French onion flavor. Gruyère is creamier and more flavorful, while Swiss cheese is a little milder and often easier to find.

SALT & BLACK PEPPER Season each component lightly as you go rather than adding a huge amount at the end. Freshly ground black pepper works especially well with the sweet onions and creamy sauce.

Step-by-Step Instructions

1. Cook the chicken

If you’re starting with raw chicken, season about 1 pound of boneless, skinless chicken breasts or thighs with salt and pepper. Cook them in a skillet over medium heat until fully cooked through, then let them rest for a few minutes before shredding.

You can also use leftover cooked chicken to make this recipe much faster. You’ll need approximately 2 cups of shredded chicken.

2. Caramelize the onions

Thinly slice 3 large yellow onions. Melt 2 tablespoons of butter with 1 tablespoon of olive oil in a large skillet over medium-low heat.

Add the onions and a small pinch of salt. Stir them every few minutes and let them cook slowly for about 25–35 minutes.

This is the step worth being patient with. The onions should shrink considerably and turn soft, glossy, and deep golden brown. If they start sticking or browning too quickly, lower the heat and add a tablespoon or two of water.

3. Add garlic and broth

Once the onions are beautifully caramelized, stir in the minced garlic and thyme. Cook for about 30 seconds, just until the garlic smells fragrant.

Pour in the chicken broth and scrape the flavorful browned bits from the bottom of the pan. Let it simmer for 2–3 minutes until most of the liquid has reduced.

Remove about half of the caramelized onion mixture and set it aside for layering and topping.

4. Prepare the creamy white sauce

In a saucepan, melt 3 tablespoons of butter over medium heat. Whisk in 3 tablespoons of flour and cook for about 1 minute. It should look smooth and lightly foamy rather than brown.

Slowly pour in 2 cups of milk while whisking constantly. Keep stirring until the sauce becomes smooth and thick enough to lightly coat the back of a spoon.

Turn the heat down and stir in ½ cup Parmesan cheese. Season with salt, black pepper, and a little extra thyme if desired.

The sauce should be creamy and pourable. If it becomes too thick, whisk in a small splash of milk.

5. Mix the chicken filling

Add the shredded chicken to the skillet with the remaining caramelized onions. Stir everything together until the chicken is evenly coated with the savory onion mixture.

Taste it before assembling. This is the perfect moment to adjust the salt and pepper.

6. Cook the lasagna noodles

Bring a large pot of salted water to a boil and cook 12 lasagna noodles according to the package directions, stopping when they’re just tender.

Drain them carefully and lay them flat on a lightly greased baking sheet or parchment paper. Keeping the noodles separated makes rolling much easier.

7. Assemble the roll ups

Spread a thin layer of the creamy sauce over the bottom of a 9×13-inch baking dish.

Place one lasagna noodle flat on your work surface. Spread a layer of chicken and caramelized onion filling over the noodle, leaving a little space at the edges. Sprinkle with a small amount of mozzarella and Gruyère.

Starting from one short end, gently roll the noodle into a neat spiral. Don’t roll it too tightly or the filling may squeeze out.

Place the roll upright or seam-side down in the baking dish. Repeat with the remaining noodles and filling.

8. Add the sauce and cheese

Pour the remaining white sauce around and over the roll ups, making sure the edges of the noodles are covered. Scatter the reserved caramelized onions over the top.

Finish with the remaining mozzarella and Gruyère. You want a generous cheese layer, but don’t completely bury the onions because those golden edges become deliciously caramelized in the oven.

9. Bake until bubbling

Cover the dish loosely with foil and bake at 375°F (190°C) for about 20 minutes.

Remove the foil and continue baking for another 10–15 minutes, until the cheese is melted, bubbling, and lightly golden around the edges.

For an extra golden top, place the dish under the broiler for 1–2 minutes at the end. Keep a close eye on it because cheese can go from golden to burnt surprisingly quickly.

10. Rest and serve

Let the French Onion Chicken Lasagna Roll Ups rest for about 5–10 minutes before serving.

That short resting time helps the creamy sauce settle and makes the rolls easier to lift without falling apart. Finish with a little fresh thyme or chopped parsley if you like, then serve while everything is warm and gooey.

Expert Tips

• Take your time with the onions. Medium-low heat gives them a deep golden color and sweeter flavor without burning the edges.
• Use freshly shredded cheese. It melts more smoothly and gives the roll ups a creamier, better-looking finish.
• Don’t overcook the noodles. Slightly firm noodles hold their shape much better when you spread, roll, and bake them.
• Keep the white sauce pourable. A sauce that’s too thick can make the roll ups dry while they bake.
• Use leftover chicken for a shortcut. Rotisserie or leftover roasted chicken works especially well and turns this into an easy weeknight dinner.
• Add the cheese while rolling. A little Gruyère or Swiss tucked inside gives every chicken lasagna roll a delicious French onion flavor.
• Let the dish rest before serving. Five to ten minutes makes the creamy sauce easier to serve and keeps the rolls intact.

Storage & Make-Ahead

Store leftover roll ups in an airtight container in the refrigerator for up to 3–4 days. You can also cover the entire baking dish tightly and refrigerate it if you’re planning to serve it later.

For reheating, place individual portions in the microwave and heat in short intervals until warmed through. For the best texture, cover the portion loosely so the pasta doesn’t dry out.

You can also reheat several roll ups in a covered baking dish at 350°F (175°C) until hot in the center. Add a small splash of milk or extra white sauce if the pasta looks dry.

These roll ups are especially good for making ahead. Assemble the entire dish, cover it tightly, and refrigerate it for up to 24 hours before baking. If baking directly from the refrigerator, add roughly 10–15 minutes to the covered baking time.

For longer storage, the assembled unbaked dish can be frozen well wrapped for up to about 2 months. Thaw it overnight in the refrigerator before baking for the most even result.

What to Serve With French Onion Chicken Lasagna Roll Ups

These roll ups are rich and creamy, so I like serving them with something fresh and simple. A crisp green salad with lettuce, cucumber, tomatoes, and a light vinaigrette makes an easy side.

Roasted broccoli, green beans, or asparagus are also excellent alongside the creamy sauce. If you’re feeding a hungry family, add warm garlic bread or a simple crusty loaf for soaking up any extra sauce.

This is a wonderful choice for a cozy weeknight dinner, but it also feels special enough for a family gathering or holiday table. You can prepare the dish ahead, refrigerate it, and bake it when everyone is ready to eat.

FAQs

What are lasagna roll ups?

Lasagna roll ups are lasagna noodles filled with ingredients such as meat, vegetables, cheese, or sauce and then rolled individually before baking. They’re a fun alternative to traditional layered lasagna and make individual portions especially easy to serve.

Can I use a different chicken in these lasagna roll ups?

Absolutely. Cooked chicken breast, chicken thighs, rotisserie chicken, or leftover roasted chicken can all work. Thigh meat gives the filling a slightly richer and juicier texture.

Can I make French Onion Chicken Lasagna Roll Ups without Gruyère?

Yes. Swiss cheese is an excellent substitute, and mozzarella with a little extra Parmesan will also work. The important thing is choosing cheeses that melt well and complement the caramelized onions.

Can I prepare these chicken lasagna roll ups ahead of time?

Yes. Assemble the dish up to 24 hours ahead, cover it tightly, and refrigerate. Bake it when you’re ready, adding a little extra time because the dish will be cold from the refrigerator.

What makes these different from regular chicken lasagna?

Instead of building several flat layers, the noodles are rolled individually around chicken, caramelized onions, and cheese. The creamy white sauce and deeply browned onions give these roll ups a flavor inspired by classic French onion soup.
