Chef’s Notes: Vegan Baked Penne Pasta Casserole
- Cook Pasta Al Dente – Don’t overcook the pasta, as it will continue to soften while baking. Aim for slightly firm (al dente) texture to hold up in the casserole.
- Customize the Veggies – Feel free to add mushrooms, zucchini, spinach, or kale to increase nutrition and texture.
- Boost Umami – A spoonful of tomato paste or a splash of balsamic vinegar stirred into the sauce adds a deeper flavor.
- Layer for Cheese Stretch – For that gooey, cheesy effect, add half the vegan mozzarella in the middle of the casserole, then layer the rest on top before baking.
- Add Fresh Herbs – A sprinkle of fresh basil or parsley before serving brightens the flavor and adds color.
- Make It Ahead – Assemble the dish up to a day in advance and refrigerate. Bake it just before serving for an easy weeknight dinner.
- Freezer Friendly – This casserole freezes beautifully. Store it in portions or whole; reheat covered in the oven at 350°F until warmed through.
- Spice It Up – Add chili flakes, a dash of hot sauce, or chopped jalapeños if you like some heat.
- Use High-Quality Vegan Cheese – Not all melt the same. Look for mozzarella that melts and browns well for best results.
- Serve with a Side – This casserole pairs great with a crisp green salad, roasted vegetables, or garlic bread for a full meal.

Directions
- Begin by preheating your oven to 375 degrees F (190 degrees C). This ensures the oven is ready when the casserole is assembled.
- Cook the penne pasta according to the package directions until al dente. Once cooked, drain the pasta thoroughly to remove excess water.
- In a large pot or Dutch oven, heat the olive oil over medium heat. Add the diced bell pepper and onion, sautéing for about 3-5 minutes until they soften.
- Add the vegan meat crumbles and minced garlic to the pot. Cook for an additional 3 minutes, stirring occasionally, until the meat substitute is lightly browned.
- Pour in the marinara sauce, fire-roasted tomatoes (with their juices), Italian seasoning, and vegan Parmesan cheese. Stir well to combine all ingredients, then remove the pot from the heat.
- Add the drained, cooked penne pasta to the pot with the sauce. Gently stir until the pasta is evenly coated with the sauce mixture.
- Transfer the pasta mixture to a 9×13 inch casserole dish. Sprinkle the remaining vegan mozzarella cheese evenly over the top of the casserole.
- Bake in the preheated oven for 20-25 minutes, or until the vegan mozzarella cheese is melted and bubbly. Let the casserole cool slightly before serving.

How long does it last in the fridge?
Store leftovers in an airtight container for up to 4–5 days. Reheat in the oven or microwave until heated through.
Can I use a different pasta shape?

What’s a good vegan parmesan substitute?
If you don’t have store-bought vegan parmesan, try blending cashews with nutritional yeast, garlic powder, and salt
