Step 1: Gather Your Ingredients
Before diving into the cooking process, make sure you have all the ingredients ready. Thanksgiving cooking can get busy, so organization is key!
For the Roasted Vegetables:
- 1 medium zucchini, sliced
- 1 red bell pepper, chopped
- 1 yellow bell pepper, chopped
- 1 cup diced butternut squash
- 1 medium carrot, thinly sliced
- 1 small red onion, sliced
- 2 tablespoons olive oil
- ½ teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon dried thyme or Italian seasoning
For the Ricotta Mixture:
- 2 cups ricotta cheese
- 1 egg (helps bind the mixture)
- ½ cup grated Parmesan cheese
- 1 teaspoon garlic powder
- Salt and pepper to taste
- 2 tablespoons chopped parsley or spinach (optional for color and nutrition)
For the Sauce:
- 3 cups marinara sauce (homemade or store-bought)
- 1 tablespoon olive oil
- 2 cloves garlic, minced
- ½ teaspoon red pepper flakes (optional for heat)
For Assembling the Lasagna:
- 9 lasagna noodles (regular or oven-ready)
- 2 cups shredded mozzarella cheese
- ½ cup grated Parmesan cheese for topping
- Fresh basil or parsley for garnish
Pro Tip: Use seasonal vegetables like pumpkin, kale, or mushrooms for a more Thanksgiving-inspired flavor profile.
Step 2: Roast the Vegetables
The secret to this lasagna’s incredible flavor lies in the roasted vegetables. Roasting caramelizes their natural sweetness and adds a delicious smoky depth that transforms the entire dish.
- Preheat your oven to 425°F (220°C).
- In a large mixing bowl, toss all the chopped vegetables with olive oil, salt, pepper, and thyme.
- Spread them evenly on a parchment-lined baking sheet. Avoid overcrowding — this ensures even roasting.
- Roast for 20–25 minutes, stirring halfway through, until the vegetables are tender and slightly golden at the edges.
Optional Flavor Boost: Add a drizzle of balsamic glaze or a sprinkle of smoked paprika before roasting for an extra layer of taste.
Once roasted, let the vegetables cool slightly before assembling.
Step 3: Prepare the Ricotta Mixture and Sauce
While the vegetables roast, you can prepare the creamy ricotta filling and the flavorful tomato sauce.
For the Ricotta Mixture:
- In a mixing bowl, combine ricotta cheese, egg, Parmesan cheese, garlic powder, and parsley.
- Mix until smooth and creamy.
- Taste and adjust seasoning with salt and pepper.
This ricotta mixture gives your lasagna a rich, velvety texture and holds the layers together beautifully.
For the Sauce:
- Heat olive oil in a saucepan over medium heat.
- Add minced garlic and red pepper flakes; sauté for about 30 seconds until fragrant.
- Stir in the marinara sauce and let it simmer for 5–7 minutes.
- Taste and adjust seasoning if needed.
Homemade Touch: You can add a spoonful of tomato paste and a pinch of sugar to balance the acidity of the tomatoes.
Now you’re ready to layer everything together!
Step 4: Assemble the Lasagna
Here comes the fun part — assembling your Thanksgiving Veg Lasagna!
- Prepare your baking dish: Lightly grease a 9×13-inch casserole dish.
- Spread a thin layer of sauce on the bottom of the dish to prevent sticking.
- Add the first layer of noodles. Place three lasagna noodles side by side (trim if needed).
- Layer with ricotta mixture. Spread half of the ricotta evenly over the noodles.
- Add roasted vegetables. Spoon half of your roasted vegetable mixture on top.
- Add sauce and cheese. Pour a layer of marinara sauce and sprinkle with mozzarella.
- Repeat the process: noodles → ricotta → roasted veggies → sauce → cheese.
- Finish with a final layer of noodles, sauce, and a generous topping of mozzarella and Parmesan.
Pro Tip: Press the layers gently with the back of a spoon as you go to ensure even stacking and compactness.
Step 5: Bake to Perfection
Now that your lasagna is assembled, it’s time to bake it into cheesy, bubbling perfection.
- Preheat your oven to 375°F (190°C).
- Cover the dish with aluminum foil (to prevent the cheese from burning) and bake for 25 minutes.
- Remove the foil and bake uncovered for another 15–20 minutes, or until the cheese is melted and golden brown.
- Let it rest for 10–15 minutes before slicing — this helps the layers set and makes serving easier.
Serving Suggestion: Garnish with fresh basil or parsley and a sprinkle of extra Parmesan before serving.

This hearty vegetable lasagna can easily be the star of your Thanksgiving feast or serve as a flavorful side alongside traditional favorites. Here are a few ways to serve it:
