This is a vegan adaptation of a pasta dish I used to make before embracing a plant-based lifestyle, and it remains a favorite in our home. In fact, our daughter often prepares this for gatherings because it’s a flavorful pasta dish that everyone can enjoy, regardless of their dietary preferences. This is a baked version of the Tomato Lentil Penne Pasta recipe from our Batch cooking with Tami Course. Use code Nutmeg30 to save 30% on any of our courses.

One of the best things about this recipe is its versatility—you can easily customize the vegetables based on your personal tastes or what you have on hand. Try swapping mushrooms for zucchini or eggplant for a delicious twist. You can use store-bought marinara sauce, but I prefer to use Well Your World’s oil-free marinara or my own Classic Marinara, which is incredibly easy to make. If you are short on time it can be served right from the pan, as everything is hot and cooked at this stage.
This is one of my favorite gluten free pastas. The flavor is good and it keeps it shape when cooked.
Choose a whole wheat pasta, gluten free pasta or your favorite legume based pasta. It works well with all of them.

For an added touch, you can transfer the pasta to a casserole dish, sprinkle it with faux parmesan, and bake it at 350°F for 20–30 minutes. This not only enhances the flavors but also helps keep the dish warm when serving buffet-style. For this version, I added Kalamata olives and after removing it from the oven sprinkle some fresh basil on top for a burst of extra flavor.
I have 2 of these casserole dishes, they go with any table setting and can go from oven to table.
Substitutions
Marinara – use store bought marinara instead of making your own
Red onion – white onion
Red bell pepper – any color of bell pepper
Lentils – white beans
Mushrooms – eggplant or zucchini
Pasta – use gluten free, legume based or whole wheat
Spinach – kale or your favorite dark leafy greens
Once your soup cubes are frozen transfer the cubes to a gallon size freezer bag. Then your molds are ready for another batch prep item.
Can this dish be frozen? Yes you can freeze it in single serving portions for future meals. I highly recommend using the 2 cup Souper Cubes freezer storage system.
