Sweet potato, broccoli and lentils need different amounts of time in a hot oven. This sheet pan broccoli sweet potato with canned lentils without cheese gives the sweet potato a head start, adds broccoli while there is still time to cook its stems, and folds in canned lentils only for the final warming stage.
The finished dish should have soft sweet potato centers, broccoli with tender stems and a little shape, and moist lentils scattered between the vegetables. Paprika, garlic and lemon provide the seasoning. A cheese topping is unnecessary, and the method does not depend on a sauce to hide overcooked vegetables. For a different potato-based side or brunch idea, see this mashed potato waffle recipe.
Use three oven stages for sheet pan broccoli sweet potato with canned lentils without cheese
- Start the sweet potato: evenly sized cubes need the longest time and benefit from direct contact with the hot pan.
- Add broccoli after the centers begin to soften: coat the florets lightly and leave room for steam to escape.
- Warm lentils near the finish: drain them well and fold them onto the tray only long enough to heat and pick up the seasoned oil.
Without cheese, the final balance comes from browned vegetables, enough salt and a bright finish. Add the measured lemon juice after roasting; chopped parsley is an optional serving finish. The tray is ready when the largest sweet-potato cube is tender, the broccoli stems yield to a fork, and the lentils remain distinct rather than dried onto the pan.
Follow the three additions
| Addition | Time before the next addition | What to check |
|---|---|---|
| Sweet potato, half the oil and half the paprika | Roast 16–18 minutes. | The cubes should be starting to soften and show color on their contact surfaces. |
| Broccoli, remaining oil and seasonings | Roast another 10 minutes. | Broccoli stems should be progressing toward tenderness; check a large potato cube too. |
| Drained canned lentils | Roast another 5–7 minutes. | Lentils are thoroughly hot, potato centers are soft, and broccoli remains in recognizable florets. |
Yield: approximately 2–3 light mains with a cooked grain, or 3–4 small side portions. Prep: 10–15 minutes. Roast: the stated stages add up to about 31–35 minutes; allow up to 40 minutes if larger pieces need longer. Total: approximately 45–55 minutes. Oven: 425°F / 220°C.

Use an 18-by-13-inch rimmed metal sheet (paid link), a mixing bowl, a fine-mesh sieve, a clean towel, a broad spatula (paid link) and a small knife for checking tenderness. If your tray cannot hold all the vegetables and lentils in a shallow layer, plan a second tray before the first roast begins.
Ingredients
- 1 medium sweet potato (about 12 ounces), diced into 3/4-inch pieces
- 2 cups small broccoli florets
- 1 can (15 ounces) brown or green lentils, drained and dried
- 2 tablespoons olive oil
- 1/2 teaspoon sweet paprika
- 1/4 teaspoon garlic powder
- 1 tablespoon lemon juice
- Salt and pepper
Prepare the shapes before measuring
Scrub the sweet potato and remove any damaged areas. Cut pieces about three-quarters of an inch across so the center of one cube is not much thicker than its neighbors. The skin may stay on if it is sound and thin enough for your preference. Dry the cut surfaces before adding oil.
Measure two cups of small broccoli florets without forcing them into a tightly packed mass. If a floret has an especially thick stem, split it lengthwise so its base can cook with the smaller florets. Drain the canned brown or green lentils in a fine-mesh sieve, then blot gently. Avoid pressing them into a paste while trying to remove every drop of moisture.
Why the lentils wait until the end
Canned lentils have already been cooked, so their job here is to become hot and pick up seasoning. They do not need the sweet potato’s full oven time. Adding them early can dry the small lentils around the pan’s edges before the center of a dense potato cube is soft.
The oil is divided equally: one tablespoon coats the sweet potato and the other coats the broccoli. Split the half teaspoon of paprika into two quarter-teaspoon portions. The garlic powder goes with the broccoli so it has a shorter time in the oven. Hold the lemon until the food is cooked, then use it to dress the whole tray.

Step-by-step oven method
- Preheat and clear the work area. Heat the oven to 425°F with a rack near the middle. Set out the rimmed pan, spatula and a heatproof landing area. Drain the lentils and prepare the vegetables before you start so later additions can go in without rushing.
- Season the sweet potato. Toss the three-quarter-inch cubes with 1 tablespoon olive oil and half of the paprika. Spread them on the pan in one layer, with a flat cut face against the metal where possible. Leave space between pieces rather than collecting them into a thick central pile.
- Roast the first stage. Cook the sweet potato for 16–18 minutes. Lift one large cube to inspect its underside and check whether its center is beginning to soften. If the pieces are unusually large and still very hard, give them a little more head start before adding broccoli.
- Coat and add the broccoli. Toss the small florets with the remaining tablespoon of oil, remaining paprika, garlic powder, and salt and pepper to taste. Add them to the spaces on the tray. Gently turn potato cubes that are browning on the bottom, then make sure the florets are not stacked over them.
- Roast for another 10 minutes. Check a thick broccoli stem and a large sweet potato cube. The vegetables should be progressing toward their finished texture. If the tray is crowded, split the food between two pans rather than stirring a pile repeatedly and expecting it to brown evenly.
- Fold in the lentils. Scatter the drained, blotted canned lentils over open areas and gently turn once so they meet a little of the oil and seasoning on the vegetables. Use the broad spatula to lift and fold rather than pressing down on the softened lentils.
- Finish the final stage. Roast another 5–7 minutes, just until the lentils are thoroughly hot, the potato centers are soft, and the broccoli stems are tender with slight resistance. If a few potato cubes remain firm, remove the finished broccoli and lentils to a clean dish and give only those cubes more time.
- Season the finished tray. Remove the pan and drizzle the tablespoon of lemon juice over the food. Fold gently, taste a spoonful containing lentils and vegetables, and adjust the salt and pepper if needed. Spoon into shallow bowls or serve as a side while warm.

Sweet potato: test the center
A small knife should pass through a large cube without a hard middle. Darkened corners can develop before the center is ready, especially if the cubes are uneven. Check more than one area of the pan, and do not hold finished broccoli in the oven solely to keep the tray together.
Broccoli: inspect the stem
The fine tips brown before a thick stem softens. Look for some color without blackened, brittle tips. If a floret is much larger than its neighbors, it needs its own check. A little firmness is desirable here, but the stem should be comfortable to bite.
Lentils: aim for moist and hot
They should remain recognizable, with no need to turn them into crisp crumbs. Stop the final roast once they are hot. A few lentils that break during folding can cling to the vegetables and are not a reason to keep cooking the entire tray.
Build the plate around what is already cooked
For a light main, serve over separately cooked rice or another grain. Put the grain in the bowl first, then spoon on a portion containing all three tray ingredients. A clean serving spoon is useful for gathering lentils left between the vegetables rather than leaving them behind on the pan.
For a smaller side, divide among three or four plates alongside a separate main dish. Chopped parsley is an optional fresh finish from the serving suggestions. Offer it at the table if some diners prefer fewer visible herbs. Keep extra foods out of the roasting pan unless you deliberately increase the space and assess their cooking needs.
Frequently asked questions
Can I use dry lentils straight from the bag?
No. Dry lentils need to be cooked separately until tender before they can replace canned lentils. This recipe has neither the liquid nor the covered simmer required to cook them on the tray. Drain fully cooked lentils well before the final warming stage.
Would red lentils work?
Red lentils often soften and break down more readily than brown or green lentils. They are not a direct substitute for the intact canned lentils intended here. A soft red-lentil mixture would coat the vegetables instead of remaining distinct between the pieces.
Can cauliflower replace broccoli?
It can be explored, but cauliflower stems may need a longer second stage. Keep the pieces small and check them before adding the lentils. Do not assume the ten-minute broccoli interval will produce the same result from a larger cauliflower floret.
Can I replace lentils with chickpeas?
Canned chickpeas give a larger, firmer bite. Drain them and add them as a late cooked-bean addition, checking that they are fully hot. The texture and final warming time may differ; this is a variation rather than an identical result.
Why are the lentils drying at the edges?
They may have joined too early or stayed in the oven while a few large potato cubes finished. Keep the lentils for the final five-to-seven-minute stage, and remove finished ingredients if slow pieces need extra cooking time.
Can I prepare the ingredients ahead?
Cut the vegetables and refrigerate them covered, keeping the broccoli and sweet potato separate. Drain the lentils into their own covered container in the refrigerator. Blot surface moisture and add the oil and seasonings shortly before each ingredient goes into the oven.

Leftovers: cool shallowly and reheat gently
Divide leftovers into shallow containers and refrigerate within 2 hours, or within 1 hour above 90°F. Store at 40°F or below and use within 3–4 days, following USDA leftovers guidance. Reheat to 165°F before serving hot, checking the center of the portion.
A skillet or oven can reduce surface moisture, but cover briefly if the lentils are drying before the vegetables warm through. A microwave is convenient for a small portion; stir or rearrange and verify the temperature. Expect the broccoli and sweet potato to soften after storage rather than regain every original browned edge.

Notes
- Yield and timing: One batch makes 2–3 light mains with a grain or 3–4 small sides. Allow 10–15 minutes to prepare and 31–35 minutes for the stated roast stages, up to 40 minutes if needed. Total: approximately 45–55 minutes.
- Pan and cuts: Use an 18-by-13-inch rimmed sheet at 425°F (220°C). Cut sweet potato into ¾-inch cubes and keep broccoli florets small. Use a second sheet if the ingredients overlap heavily.
- Three additions: Roast sweet potato for 16–18 minutes, add broccoli for 10 minutes, then add drained canned lentils for 5–7 minutes. Divide the oil equally between potato and broccoli, and divide the paprika into two ¼-teaspoon portions.
- Doneness: Check a large potato center and a thick broccoli stem. Lentils should be hot and moist, not dried into crumbs. Remove finished components if larger potato pieces need longer. Finish with lemon off heat.
- Leftovers: Refrigerate shallow portions within 2 hours, or 1 hour above 90°F (32°C), at 40°F (4°C) or below. Use within 3–4 days and reheat to 165°F (74°C). FoodSafety.gov storage guidance.
