Ingredients

Here’s everything you’ll need to create the ultimate vegan baked spaghetti. Each ingredient plays a key role in bringing flavor, texture, and nutrition to the dish.

Equipment

• Large pot (for boiling spaghetti)
• Large skillet or sauté pan (for sauce and veggies)
• Colander (to drain pasta)
• Mixing spoon or spatula
• 9×13-inch baking dish (or similar casserole dish)
• Measuring cups and spoons
• Cutting board & knife
• Aluminum foil (to cover during baking)

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with olive oil or nonstick spray.
2. Cook the spaghetti: Bring a large pot of salted water to a boil. Add the spaghetti and cook until just al dente, about 1-2 minutes less than package instructions. (The pasta will continue to cook in the oven.) Drain and set aside.
3. Sauté the vegetables: While the pasta cooks, heat 2 tablespoons olive oil in a large skillet over medium heat. Add the diced onion and cook for 3-4 minutes, until softened. Stir in the garlic and cook for 1 minute, until fragrant.
4. Add the bell pepper, mushrooms, and grated carrot. Sauté for 5-7 minutes, until the vegetables are tender and most of the moisture has cooked off.
5. Make the sauce: Add the crushed tomatoes, tomato paste, Italian seasoning, and red pepper flakes (if using) to the skillet. Stir well to combine, then add the cooked lentils. Simmer the mixture for 10 minutes, stirring occasionally, until slightly thickened.
6. Wilt in the spinach: Stir in the baby spinach and cook for 1-2 minutes, until wilted. Taste and season with salt and black pepper as needed.
7. Combine pasta and sauce: In a large bowl, toss the drained spaghetti with the sauce mixture until evenly coated.
8. Assemble the casserole: Spread half of the spaghetti mixture into the prepared baking dish. Sprinkle with half the vegan mozzarella cheese. Layer the remaining spaghetti mixture on top, then finish with the rest of the cheese.
9. Bake: Cover the dish with aluminum foil and bake for 20 minutes. Remove the foil and bake for another 10-15 minutes, until the cheese is melted and bubbly, and the top is golden in spots.
10. Garnish and serve: Let the casserole cool for 10 minutes before slicing. Top with fresh basil or parsley, if desired. Serve hot and enjoy!

Tip: For an extra-crispy top, broil the casserole for 2-3 minutes after baking. Keep a close eye to avoid burning the cheese!

Tips & Variations

• Swap the protein: Replace lentils with vegan sausage, crumbled tofu, or store-bought vegan “beef” for a different twist.
• Go gluten-free: Use your favorite gluten-free spaghetti noodles for a wheat-free version.
• Add more veggies: Zucchini, eggplant, kale, or broccoli all work wonderfully in this casserole. Just sauté them with the rest of the veggies.
• Cheese options: Try a blend of vegan mozzarella and vegan parmesan for extra flavor. Nutritional yeast also adds a cheesy, nutty note.
• Make it ahead: Assemble the casserole up to a day in advance and refrigerate. Bake when ready to serve, adding 5-10 minutes to the bake time.
• Spice it up: Add a pinch of smoked paprika or a splash of hot sauce to the sauce for an extra kick.
