This vegan vegetable casserole with baked veggies is packed with flavor from juicy marinara sauce to hearty vegetables and the sharpness of vegan cheese. It's like a garden in a casserole dish and is also perfect after a trip to the Farmers' Market!
And if you double-check the ingredients you use, you can also very easily make this dish gluten-free.
My husband does not eat vegan, so we are always looking for dishes he can pair with the meat of his choice (he likes grilled chicken or grilled fish with this). He loves this vegan vegetable casserole with baked veggies for this exact purpose!
Vegan pairings: I like to add a handful of pasta to mine to make it a full meal. Or, I eat it like a curry over rice and a handful of chickpeas for protein. If you want a completely grain-free meal, however, you can add it over a bed of cauliflower rice and/or sauteed kale.
We also love to meal prep, and this one gives us 6-8 very filling servings in an hour. It's also a great dinner party dish!
Cooking Note: I do recommend cooking the vegetables prior to baking them, even though some recipes just toss them in and bake. While just baking saves time, cooking the vegetables prior really helps their unique flavors stand out. It's worth it!
Before we get to the recipe, I am picky about quality ingredients, and I do recommend certain ingredients for this dish.
Best Ingredient Recommendations
For the most authentic style dish, use these specific ingredients. You can buy easily buy them on Amazon below:
- Bianci DiNapoli tomato sauce: This sauce hails from James Beard Award-Winning Restaurateur Chris Bianco and 3rd Generation Tomato Processor Rob DiNapoli. We buy it at our local Italian Market, and I can't imagine eating any other tomato-based sauce. It's as juicy, flavorful, and fresh as if the tomatoes were picked in your own garden.
- Violife mozzarella shreds: I'm very picky about vegan cheese, and this is one of the very few cheeses I do recommend. It's highly rated on Amazon, used by my local award-winning vegan pizza place and satisfies even my non-vegan husband. It's pretty darn close to "the real thing." It's also gluten-free.
