Step-by-Step Instructions
- Prep Your Oven and Herbs:
- Preheat your oven to four hundred degrees Fahrenheit for even heat Start with a hot oven so everything cooks uniformly Mix all herb and spice ingredients in a small bowl and set aside Mixing the herbs first releases their oils and aromas making a tastier dish
- Layer and Season the Vegetables:
- Place sliced onions diced bell pepper potato wedges minced garlic and thick zucchini rounds into a deep ceramic or enamel lined Dutch oven Add canned tomatoes and selected amount of vegetable broth next Sprinkle baking soda over everything Add the herb and spice mixture on top Carefully mix until all pieces are evenly coated which ensures maximum flavor throughout Avoid over mixing which can break down the potatoes
- Begin Baking Covered:
- Sprinkle the top lightly with extra salt and black pepper if desired Put a tight fitting lid on the pot and place it in your preheated oven Roast covered for forty minutes The lid locks in moisture and helps the potatoes soften without drying out
- Add Beans and Finish Baking:
- After forty minutes carefully remove the pot from the oven Lift the lid away from you to avoid steam Mix the cannellini beans gently into the vegetables then cover and return to the oven Bake for an additional five to twenty minutes until the potatoes are fork tender The baking time depends on the size of your potato wedges Use a fork to test for doneness
- Rest and Serve:
- Once done remove the pot from the oven take off the lid and let the bake sit uncovered for about ten minutes Letting it rest helps the flavors settle and makes serving easier Remove the bay leaves before dishing up
- Finish with Toppings:
- Serve portions topped with a sprinkle of nutritional yeast or vegan Parmesan cheese plus some fresh parsley and a pinch of red pepper flakes for a lively finish

I have always loved the gentle sweetness that the roasted onions add They almost melt into the rich tomato gravy My mother taught me to save a little chopped parsley for serving which always makes the plate sunny and bright
Storage Tips
Let the bake cool completely before storing Place leftovers in an airtight container and refrigerate for up to four days For freezing allow to cool then place in freezer safe containers The texture of potatoes and zucchini will be softer after thawing but all the flavors stay delicious
Ingredient Substitutions
You can swap the cannellini beans with navy beans or chickpeas if that is what you have on hand For a different flavor try yellow squash or eggplant in place of zucchini If you like smoky depth add a dusting of smoked paprika with the herbs
Serving Suggestions
This bake is filling on its own but also makes a great side with crusty bread or over quinoa For a more festive feel serve alongside a crisp green salad and a drizzle of good olive oil
