How To Make Pioneer Woman White Vegetable Lasagna
- Prep and grill the squash: Preheat the oven to 350°F. Heat a grill pan over medium-high heat. Toss the squash strips with olive oil, salt, and pepper. Grill the squash for about 2 minutes per side, until grill marks appear. Set aside.
- Cook the spinach: In a large skillet, heat olive oil over medium heat. Add the spinach in batches and cook until just wilted, about 2 minutes. Season with salt and pepper. Transfer the spinach to a paper-towel-lined plate to drain all excess liquid.
- Make the white pesto sauce: In the same skillet, melt the butter over medium heat. Cook the garlic and onion until softened, about 2 minutes. Whisk in the flour to form a roux and cook for 2 more minutes. Slowly whisk in the warmed milk and cream until smooth. Cook until the sauce thickens, about 3-4 minutes. Remove from heat and season. Whisk in the Parmesan and pesto, then fold in the chopped artichoke hearts.
- Prepare the ricotta mixture: In a medium bowl, mix the ricotta cheese, Parmesan, egg yolks, salt, and pepper until well combined.
- Assemble the lasagna layers: Butter a 13×9-inch baking dish. Spread 1 cup of sauce on the bottom. Layer with 4 noodles, 1 ½ cups of sauce, all the spinach, and ½ cup mozzarella. Add 4 more noodles, 1 ½ cups of sauce, all the ricotta mixture, and ½ cup mozzarella. Add 4 more noodles, 1 ½ cups of sauce, ½ cup mozzarella, and the grilled squash slices. Top with the last 4 noodles, the remaining sauce, and the remaining 1 cup of mozzarella.
- Bake and rest: Bake for 40 to 45 minutes, until browned and bubbly. Let the lasagna rest for 10 to 20 minutes before slicing and serving. Top with fresh basil.

Recipe Tips
- How to prevent a watery lasagna? It is crucial to drain the cooked spinach very well. Squeeze out as much liquid as possible with your hands or by pressing it against a sieve.
- Can I use regular lasagna noodles? Yes, but you will need to cook them first according to the package directions until they are al dente.
- How to get perfectly grilled squash without a grill pan? You can roast the squash strips on a baking sheet at 400°F for 10-15 minutes, flipping halfway through, until tender and lightly browned.
- Can I make this ahead of time? You can assemble the entire lasagna (without baking) up to a day in advance. Cover it tightly and refrigerate. You may need to add 10-15 minutes to the baking time.
What To Serve With White Vegetable Lasagna

How To Store White Vegetable Lasagna
- Refrigerate: Cover leftovers tightly or transfer to an airtight container. Store in the refrigerator for up to 5 days.

FAQs
Can I add chicken to this recipe?
Absolutely. To make it a white chicken lasagna, you can add 2 cups of shredded, cooked rotisserie chicken. The best place to layer it in would be on top of the spinach layer before you add the mozzarella.
Why is my white sauce lumpy?
Lumps usually form when the liquid is added too quickly to the flour-butter mixture (roux). To ensure a smooth sauce, add the warmed milk and cream very slowly at first, whisking constantly until smooth before adding the rest.
Can I use different vegetables?
Yes, this recipe is adaptable. You could substitute the squash with grilled zucchini or add a layer of sautéed mushrooms along with the spinach.
