Ingredients

• 9 lasagna noodles
• 2 cups butternut squash, peeled and diced
• 2 cups fresh spinach
• 15 oz ricotta cheese
• 2 cups mozzarella cheese, shredded
• 1 cup Parmesan cheese, grated
• 1 egg
• 2 cups marinara sauce
• 2 tablespoons olive oil
• Salt and pepper to taste
• Italian seasoning to taste

Spotlight: the butternut squash is the star — slightly sweet, velvety when cooked, and it makes the whole thing cozy. If you like, use roasted squash instead of sautéed for deeper flavor. Substitutions? Swap ricotta for cottage cheese (blended smooth) or use part-skim cheeses if you want lighter options; gluten-free noodles work fine. Spinach can be swapped with kale (massage it first) or chard. Health note: squash and spinach add fiber, vitamin A, and iron casually — not clinical talk, just real benefits. I buy mine at the local farmers’ market or Trader Joe’s in Austin (seasonal bargains there!). Want to save money? Buy bulk cheese on sale, or use half the Parmesan — still great. Experiment! Make it yours. (Parenthetical personal aside: I always snag a huge squash when it’s cheap, roast extras, stash in freezer.)

The Process Overview

1. Preheat the oven to 375°F (190°C).
2. In a skillet, heat olive oil over medium heat. Add diced butternut squash, salt, and pepper, and cook until softened, about 5-7 minutes.
3. Stir in spinach until wilted, then remove from heat.
4. In a bowl, mix ricotta cheese, egg, Italian seasoning, salt, and pepper.
5. Spread a thin layer of marinara sauce on the bottom of a 9×13 inch baking dish.
6. Layer 3 lasagna noodles over the sauce.
7. Spread half the ricotta mixture, followed by half the butternut squash and spinach mixture, and one-third of the mozzarella.
8. Repeat layers: sauce, noodles, remaining ricotta mixture, remaining butternut squash and spinach mixture, and another layer of mozzarella.
9. Top with remaining noodles, marinara sauce, mozzarella, and Parmesan cheese.
10. Cover with foil and bake for 25 minutes.
11. Remove foil and bake an additional 15 minutes, or until cheese is bubbly and golden.
12. Let sit for 10 minutes before serving.

Start-to-finish this is around an hour with some hands-on time of 20–30 minutes. Don’t worry about perfect noodle placement — imperfect is charming, honestly. If your squash seems slightly firm, give it a few extra minutes in the skillet; slight caramelization is great. Foil on for the first bake keeps moisture in; foil off for the last bit = bubbly golden perfection. If the top browns too fast, tent it. Patience: let it sit 10 minutes — set slices so they don’t fall apart. You can do this!!! Troubleshooting: watery ricotta? Drain it a little. Noodles stubborn? Break them to fit. No stress.

Tips & Tricks

Make-ahead? Yes — assemble, cover, and refrigerate up to 24 hours before baking; add 10–15 minutes to bake time if cold. Freeze? Cool completely, wrap tightly, freeze for up to 3 months. Thaw overnight and bake covered, then uncover to brown. Reheating: microwave slices for a quick lunch, or reheat in oven at 350°F for 15–20 minutes covered to restore texture. Batch cooking: double it and freeze extras for busy weeks — life saver. Kid-friendly tweaks: add a thin layer of hidden pureed carrots or applesauce to the squash for extra sneaky nutrition; mild cheeses help with picky eaters. Teacher-voice tip: label and date your containers — organization = peace. For another cozy squash idea, try my other butternut squash orzo, it’s similar vibes and great for variety!

Serving Ideas & Pairings

Serve with a crisp green salad, crusty bread, or simple roasted Brussels sprouts. Want something light? A citrusy arugula salad cuts the richness. Hosting a dinner? Make it a buffet with garlic bread and a simple antipasto. My go-to: a lemony spinach salad and a dollop of extra ricotta on the side. Leftovers? Add to a breakfast bake, or top with an egg for brunch — unexpected and so satisfying. Try it for holidays, potlucks, or a cozy date night at home. Pretty please try it — you’ll love it, I promise.
