How to Make One-Pan Chicken and Broccoli Lasagne Recipe

Step 1: Cook the Chicken

Start by heating your olive oil in a large, heavy-based pan over medium heat. Season your thin chicken steaks with salt and freshly cracked black pepper, then cook them for about 5 to 6 minutes until just done. The key here is to allow the chicken to rest before shredding it with forks — this keeps it juicy and tender, giving you that perfect shredded texture you want in your lasagne.

Step 2: Build the Sauce Base

With the chicken temporarily set aside, use a splash of water to deglaze the pan, scraping up any sticky, flavorful brown bits left behind. This step is pure magic for flavor. Add the butter, diced onion, and minced garlic to the pan, stirring them together for a couple of minutes until you get that sweet, aromatic base forming.

Step 3: Sauté the Leek

Next, toss in the finely sliced leek and cook gently, stirring for about 3 to 4 minutes until it softens beautifully. The leek adds a delicate sweetness and extra body to the sauce, rounding out the flavor profile wonderfully.

Step 4: Thicken the Sauce

Sprinkle the plain flour over the softened veggies and stir continuously for a full minute to cook out that raw flour taste. This is essential for achieving a creamy, thick consistency that clings to every piece of chicken and broccoli.

Step 5: Add the Liquids and Herbs

Gradually pour in your chicken stock, stirring constantly to combine. Then add the rich thickened cream along with Italian mixed herbs, salt, and pepper for seasoning. Bring everything up to a gentle simmer – this is where the sauce transforms into a silky and flavorful base ready to envelop your lasagne sheets.

Step 6: Incorporate the Broccoli and Chicken

Gently stir in the roughly chopped broccoli florets and shredded chicken. The broccoli adds brightness and a welcome crunch, while the chicken brings savory, protein-packed comfort. Let it all simmer together briefly to marry the flavors perfectly.

Step 7: Layer the Lasagne Sheets

Using tongs, carefully add your fresh lasagne squares into the pan, making sure they’re fully submerged and evenly spread. This one-pan method means the sheets cook right in the sauce, soaking up all that creamy goodness and keeping every bite tender without fussing over separate layers.

Step 8: Top with Cheese and Bake

Sprinkle the grated parmesan and mozzarella evenly over the top of your lasagne in the pan. Place the pan under a hot grill until the cheese melts and bubbles into a golden crust. This finishing touch makes the dish irresistible, adding depth with its rich, melted cheese topping.

Make Ahead and Storage

Storing Leftovers

If you have any leftovers from this One-Pan Chicken and Broccoli Lasagne Recipe, store them in an airtight container in the fridge for up to three days. The flavors will deepen, and reheated portions still taste wonderfully comforting.

Freezing

This lasagne freezes beautifully. Portion it into freezer-safe containers and freeze for up to two months. Just make sure to cool it completely before freezing to maintain texture and flavor.

Reheating

Reheat leftovers gently in the oven at 180°C (350°F) or in the microwave, covered to keep moisture in. Add a splash of cream or chicken stock if the sauce has thickened too much during storage to revive that luscious texture.

FAQs

Can I use dried lasagne sheets instead of fresh?

Yes! If you opt for dried lasagne sheets, be sure to use a bit more liquid or pre-soak them to prevent dryness, as they take longer to cook through than fresh sheets.

Is it possible to make this recipe vegetarian?

You can easily swap the chicken for firm tofu or mushrooms and use vegetable stock to keep it vegetarian while maintaining the rich flavors and texture.

What can I substitute for thickened cream?

Greek yogurt or evaporated milk can be used in a pinch to reduce calories, but keep in mind the sauce may be slightly less rich and creamy.

Can I prepare this dish ahead of time?

Absolutely! Assemble the dish up to the baking step, cover, and refrigerate for up to 24 hours before baking and grilling the cheese topping.

How do I know when the lasagne sheets are cooked through?

The fresh sheets become tender and easily pierced with a fork when evenly submerged in the sauce and simmered gently, as you do in this one-pan method.
