What veggies can you put on a sandwich?
- There is no main protein source in these sandwiches, but I still found them to be really filling and satisfying. You could easily add shredded chicken or turkey, or your favorite deli meat if you wanted!
- You can switch up the combination of roasted vegetables to fit your preference as needed. Other vegetables that would roast up well and be great in this sandwich would be (from longest to shortest times) butternut squash, Yukon gold potatoes, turnips, carrots, eggplant, yellow squash, onion, and bell peppers.
- You can also customize the spreads and other toppings; pesto would be great in place of hummus, and cream cheese or goat cheese would be so good in place of ricotta.
- You could use leafy greens in place of or in addition to the sprouts.
- If you don’t have sandwich bread, this would make a great wrap or filling in a pita pocket!

How do you make a roasted veggie sandwich not soggy?
- Roasted vegetables tend to leak out a lot of moisture after roasting. The best way to keep your sandwich from getting soggy is to keep your fillings separate until you’re ready to eat.
- Using spreads like ricotta and hummus in this roasted veggie recipe act as a “barrier” to keep the moist vegetables from touching the bread, which you want to stay dry.
- Using greens (like micro greens in this recipe) also helps reduce the amount of moisture getting to your bread in sandwiches.
Ingredient Notes and Tips
- Roasting matters: Roast vegetables until tender and lightly caramelized. This improves flavor and reduces excess moisture.
- Let veggies cool: Allow roasted veggies to cool before storing. This helps prevent sogginess later.
- Layer strategically: Spreads go directly on the bread to act as a moisture barrier. Greens sit between spreads and veggies.

How to Store and Reheat
This recipe works best when components are stored separately.
- Store roasted veggies in an airtight container for 3–4 days.
- Store bread separately at room temperature or in the fridge.
- Assemble sandwiches the day you plan to eat them for best texture.
These sandwiches are great cold or at room temperature. Reheating the veggies is optional. Toast the bread if you want a warm, crispy bite.

FAQs
Yes. The key is storing components separately. Roasted vegetables release moisture after cooking, so keep them in their own container. Use spreads like hummus or ricotta on the bread to create a barrier, and add greens between the spread and veggies.
Not necessarily. The roasted vegetables and spreads make these sandwiches satisfying on their own. If you prefer extra staying power, you can add chicken, turkey, or beans without changing the structure of the recipe.
No. This recipe is not freezer-friendly. The vegetables and bread don’t hold up well once thawed and can become watery and mushy.
Roasted vegetables last about 3–4 days in the refrigerator when stored in an airtight container. For best flavor and texture, use them within that window.

Roasted Veggie Sandwiches
Ingredients
For the roasted vegetables
- 1 large beet peeled
- medium sweet potato peeled
- 1 medium zucchini
- 3 tsp olive oil
- 1.5 tsp dried thyme
- 1.5 tsp dried oregano
- salt and pepper
For everything else
- 1/2 cup hummus
- 1/2 cup riccotta cheese sub cream cheese
- 3 oz alfalfa sprouts sub fresh greens of your choice
- 6 slices bread of choice
Instructions
- Prepare the vegetables. Preheat your oven to 375F (190C). Prepare 2 baking sheets with foil, parchment, or a silicone baking mat. Carefully slice beets, sweet potatoes, and zucchini into 1/4 inch (.6 cm) strips. In a medium-sized bowl, toss the sliced beets with 1/3 of the olive oil, 1/3 of the herbs, and seasonings (you will be doing this three times). Toss with tongs or hands until beets are completely coated and then lay them on the prepared baking sheet. Repeat this process with the sweet potato and line on the same baking sheet if there is still room, making sure they are not touching. Finally, add the zucchini slices to the bowl with the remaining oil, herbs, and salt, and pepper and toss to combine. Set aside for now.
- Bake the beets and sweet potatoes for 20 minutes, then take the pan out and flip so they brown evenly. Add the sliced and seasoned zucchini to the second baking sheet and spread them out evenly so they are not touching. Bake for 10 minutes.
- After 10 minutes, check on all the veggies to see if they are fork-tender and slightly darkened. The beets and zucchini may need 5-10 minutes more. Remove the vegetables from the oven when they are fork-tender and slightly darkened. Allow to cool completely before storing in a container.
- Assemble the sandwiches. The sandwich will taste best made the same day you eat it. No need to reheat the roasted veggies unless desired. Toast the bread if desired, and top one slice of bread with about 2 tbsps ricotta, and the other slice with about 2 tbsp hummus. On top of the hummus, layer 2-3 slices of beets, sweet potatoes, and zucchini. On the other slice, press the sprouts into the ricotta. Cut the sandwich in half and enjoy!
Notes

- Instead of hummus, try pesto
