How to roast vegetables without oil
Use a hot oven, dry the vegetables well, and leave space between pieces so they roast instead of steam. A small amount of broth helps the seasonings adhere. Turning the vegetables once encourages even browning on the parchment-lined pan.
Oil-Free Sheet-Pan Roasted Vegetables tips
- First, cut root vegetables a bit smaller than softer vegetables so everything finishes together.
- Next, pat vegetables dry after rinsing to reduce steam and encourage browning.
- Meanwhile, preheat the oven fully so the pan is hot when the vegetables join it.
- For extra caramelization, spread vegetables in a single layer and use two pans if needed.
Ingredients
Original recipe (1×) yields 4 servings
- 1 medium sweet potato, peeled and cut into 3/4-inch cubes (about 1 1/2 cups)
- 2 cups broccoli florets
- 2 cups cauliflower florets

- 1 yellow bell pepper, cut into 1-inch pieces

- Whisk together the vegetable broth, lemon juice, smoked paprika, garlic powder, thyme, salt, and black pepper.

Serving ideas
Pair these vegetables with white chicken chili, lentil soup, quinoa, farro, or a leafy green salad. Leftovers also make a convenient filling for wraps and grain bowls. For more plant-forward ideas, visit The Nutrient.
Variations
- Autumn pan: Replace the broccoli with cubed butternut squash and add fresh sage.
- Mediterranean: Use oregano instead of thyme and finish with lemon zest.
- Spicy: Add 1/4 teaspoon cayenne or crushed red pepper.
Substitutions and swaps
- If you don’t have low-sodium vegetable broth, use plain water plus an extra 1/2 teaspoon lemon juice and a pinch more salt.
- If you prefer a touch of oil for flavor, add 1 tablespoon extra-virgin olive oil before roasting; however, this changes the heart-health rating below.
- To make this recipe nut-free or allergy-friendly, simply omit parsley or swap for chives.
Save Time
- Measure the ingredients and prepare the produce before cooking so the recipe comes together without pauses.
Storage and reheating
Refrigerate cooled vegetables in an airtight container for up to four days. Reheat on a parchment-lined sheet pan at 400°F for 8 to 10 minutes to restore the roasted texture. If you prefer, gently reheat single servings in a skillet over medium heat for 4 to 6 minutes.

This recipe earns a 5-of-5 hearts rating because it is plant-based and contains no meat, dairy, eggs, or cooking oils. If you add a cooking oil (for example, 1 tablespoon olive oil), deduct one heart, resulting in a 4-of-5 rating. For an oil-free alternative to added oil, increase the broth by 1 tablespoon and roast at the same temperature.
