Ready to turn your sheet pan into the MVP of your kitchen? Let’s roast.

1. Smoky Chili-Lime Cauliflower Steaks With Cilantro “Crema”

These thick-cut cauliflower steaks roast up tender with crispy edges and a smoky, zesty kick. The bright lime and herby “crema” (no dairy in sight) make this feel restaurant-level without any fuss. Perfect as a main with a side salad or piled over mashed sweet potatoes.

Ingredients:

• 2 large heads cauliflower, sliced into 1 to 1.5-inch “steaks”
• 3 tbsp olive oil
• 1.5 tsp smoked paprika
• 1 tsp chili powder
• 1/2 tsp ground cumin
• 1/2 tsp garlic powder
• 1/2 tsp onion powder
• 1 tsp fine sea salt
• 1/2 tsp black pepper
• 1 lime, zested and juiced (divided)
• 1/3 cup compliant mayonnaise
• 1/4 cup fresh cilantro, chopped (plus extra for garnish)
• 1 clove garlic, finely grated

Instructions:

1. Preheat the oven to 425°F (220°C). Line a large baking sheet with parchment.
2. Whisk olive oil, smoked paprika, chili powder, cumin, garlic powder, onion powder, salt, pepper, and half the lime zest.
3. Brush both sides of the cauliflower steaks with the spice oil and arrange on the sheet (use any loose florets too).
4. Roast 20 minutes, flip carefully, then roast 10-15 minutes more until deeply browned and tender.
5. Meanwhile, make the cilantro “crema”: Stir mayonnaise, cilantro, garlic, remaining lime zest, and 1 tbsp lime juice. Thin with a splash of water if needed; season to taste.
6. Drizzle the crema over the hot steaks, finish with extra cilantro and a squeeze of lime.

Serve with avocado slices and crunchy radishes for contrast. Want heat? Add crushed red pepper or a dash of compliant hot sauce. For extra protein, top with a fried egg or shredded rotisserie chicken (check for compliance).

2. Maple-Chili Brussels Sprouts With Crispy Prosciutto Crumbs

These Brussels sprouts hit all the sweet-spicy-savory notes. They’re roasted until the edges turn lacy and crisp, then tossed with a sticky maple-chili glaze. The crispy prosciutto “crumbs” on top make it feel indulgent—without breaking Whole30 rules.

Ingredients:

• 1.5 lbs Brussels sprouts, trimmed and halved
• 3 tbsp olive oil
• 1 tsp fine sea salt
• 1/2 tsp black pepper
• 1/2 tsp garlic powder
• 2 tbsp pure maple syrup (Whole30-compatible for cooking, not as a sweetener—use sparingly)
• 1 tsp red pepper flakes (adjust to taste)
• 1 tbsp apple cider vinegar
• 3 oz thinly sliced prosciutto
• Zest of 1 lemon

Instructions:

1. Preheat oven to 425°F (220°C). Toss Brussels with olive oil, salt, pepper, and garlic powder on a sheet pan. Place cut side down for maximum caramelization.
2. Roast 18-22 minutes until browned and tender.
3. While they roast, line another small tray with parchment. Lay prosciutto slices in a single layer. Bake for 8-10 minutes until crisp. Cool, then crumble into “crumbs.”
4. Whisk maple syrup, red pepper flakes, and apple cider vinegar.
5. Transfer hot Brussels to a bowl, toss with the maple-chili mixture, then scatter over the prosciutto crumbs and lemon zest.

Serve these alongside roast chicken or salmon. If you’re avoiding the maple altogether, sub in extra vinegar and a splash of compliant balsamic for tang, plus a pinch of smoked paprika for complexity. Save leftover prosciutto crumbs for salads—if they last that long.

3. Garlicky Herb Sheet-Pan Ratatouille With Olive Gremolata

Think classic ratatouille but roasted—meaning deeper flavor and fewer steps. The mix of eggplant, zucchini, peppers, and tomatoes gets jammy and sweet in the oven. A bright olive gremolata wakes it all up and makes it feel fancy with basically zero effort.

Ingredients:

• 1 medium eggplant, cut into 1-inch cubes
• 2 medium zucchini, sliced into half-moons
• 1 red bell pepper, sliced
• 1 yellow bell pepper, sliced
• 1 red onion, sliced
• 2 cups cherry tomatoes
• 4 tbsp olive oil
• 1.5 tsp fine sea salt
• 1/2 tsp black pepper
• 1 tsp dried oregano
• 1 tsp dried thyme
• 4 cloves garlic, minced
• 2 tbsp tomato paste
• 2 tbsp balsamic vinegar (check compliance)

Olive Gremolata:

• 1/2 cup parsley, finely chopped
• 1/3 cup pitted green olives, chopped
• 1 clove garlic, very finely minced
• Zest of 1 lemon
• 2 tbsp olive oil

Instructions:

1. Heat oven to 425°F (220°C). Pile all vegetables on two sheet pans to avoid crowding.
2. Whisk olive oil, salt, pepper, oregano, thyme, minced garlic, tomato paste, and balsamic. Toss with the vegetables to coat.
3. Roast 25-30 minutes, stirring once, until tender and caramelized at the edges.
4. Mix gremolata ingredients in a small bowl.
5. Transfer roasted veggies to a platter and spoon the olive gremolata over the top.

Serve with seared shrimp or grilled chicken. For a cozier vibe, add a spoonful of compliant pesto instead of the gremolata. Leftovers are phenomenal with a runny egg on top—seriously, try it.

4. Harissa-Roasted Carrots With Toasted Almonds And Orange-Tahini Drizzle

These carrots go sweet-spicy with a North African twist. Harissa brings warmth, orange adds brightness, and the tahini drizzle makes everything feel luxurious. It’s the side dish you make once and start craving weekly.

Ingredients:

• 2 lbs carrots, peeled and cut into thick batons or left whole if thin
• 3 tbsp olive oil
• 1.5 tbsp harissa paste (check for compliant ingredients)
• 1 tsp ground coriander
• 1/2 tsp ground cumin

• Pinch of salt

Instructions:

1. Heat oven to 425°F (220°C). Toss carrots with olive oil, harissa, coriander, cumin, salt, pepper, and orange zest. Spread on a sheet pan.
2. Roast 25-35 minutes, shaking pan halfway, until tender and golden at the edges.
3. Toast almonds in a dry skillet over medium heat for 3-4 minutes until fragrant. Set aside.
4. Whisk tahini, orange juice, lemon juice, garlic, and enough water to create a drizzleable sauce. Season with a pinch of salt.
5. Transfer carrots to a platter, drizzle with tahini sauce, sprinkle almonds, and finish with herbs and a splash of orange juice.

Pair with roasted cod or spiced turkey meatballs. No harissa? Use smoked paprika, a pinch of cayenne, and extra lemon. For meal prep, roast a double batch—these reheat beautifully.

5. Crispy Za’atar Broccoli And Sweet Potato Bowls With Lemon-Garlic Sauce

This combo is all about texture: crackly broccoli florets and creamy, caramelized sweet potatoes. Za’atar brings that herbal, sesame crunch, while the lemon-garlic sauce ties it all together. Build a bowl with greens and protein, and you’re in business.

Ingredients:

• 1 large head broccoli, cut into small florets (save stems for another use)
• 2 medium sweet potatoes, peeled and cut into 1-inch cubes
• 4 tbsp olive oil, divided
• 1.5 tsp fine sea salt, divided
• 1/2 tsp black pepper
• 2 tbsp za’atar (check for compliant ingredients, especially no added sugar)

• 1/4 tsp crushed red pepper (optional)
• 1 lemon, zested

Lemon-Garlic Sauce:

• Pinch of salt and pepper

Instructions:

1. Preheat oven to 450°F (230°C). Toss sweet potatoes with 2 tbsp olive oil, 3/4 tsp salt, and black pepper. Spread on a sheet pan and roast for 10 minutes to get a head start.
2. Meanwhile, toss broccoli with remaining 2 tbsp olive oil, 3/4 tsp salt, garlic powder, za’atar, and red pepper (if using).
3. Add broccoli to the sheet pan. Roast everything another 15-20 minutes, until sweet potatoes are caramelized and broccoli edges are crisp.
4. Whisk sauce ingredients. Adjust lemon or salt to taste.
5. Sprinkle lemon zest over the roasted veggies and serve with generous dollops of the sauce.

Build a bowl with arugula, cucumber, and sliced avocado. Add grilled chicken, tuna, or a soft-boiled egg for protein. If you don’t have za’atar, mix sesame seeds, dried thyme, sumac (if available), and a pinch of salt—it’s a decent stand-in.

6. Balsamic-Rosemary Mushrooms And Onions Over Garlicky Mashed Cauliflower

Ultra-savory and totally comforting, this is a steakhouse side that moonlights as a main. The mushrooms and onions get glossy and rich in a balsamic reduction, then you spoon them over creamy mashed cauliflower. Weeknight luxury, no butter needed.

Ingredients:

• 1 large head cauliflower, cut into florets
• 1 tbsp olive oil (for mash)
• 2 cloves garlic, smashed
• 1/2 tsp fine sea salt, plus more to taste
• Fresh black pepper to taste
• 1.5 lbs cremini or baby bella mushrooms, sliced
• 1 large yellow onion, thinly sliced
• 3 tbsp olive oil (for sauté/roast)
• 2 tsp fresh rosemary, finely chopped
• 2 tbsp balsamic vinegar (compliant)
• 1 tsp coconut aminos

Instructions:

1. Heat oven to 425°F (220°C). Toss mushrooms and onions with 3 tbsp olive oil, rosemary, 1/2 tsp salt, and black pepper. Spread on a sheet pan.
2. Roast 20-25 minutes, stirring once, until mushrooms release their juices and edges deepen in color.
3. Meanwhile, steam cauliflower florets with smashed garlic until very tender, 8-10 minutes. Drain well.
4. Blend cauliflower with 1 tbsp olive oil, salt, and pepper until creamy. Taste and adjust seasoning.
5. Return the mushrooms and onions to the oven for 3-5 more minutes after tossing with balsamic and coconut aminos so they glaze slightly.
6. Spoon the mushrooms and onions over the mashed cauliflower. Finish with extra rosemary if you like.

Serve as a base for seared chicken thighs or sliced steak. Want extra depth? Add a splash more balsamic and a crack of pepper right before serving. If your mash seems watery, reheat it in a saucepan to evaporate moisture until fluffy.

7. Turmeric-Ginger Roasted Butternut Squash With Coconut-Lime Scallion Oil

A golden, cozy tray bake that smells like sunshine. Earthy turmeric and ginger love sweet squash, and the coconut-lime scallion oil adds a bright, glossy finish. This one’s fantastic for meal prep and shines on any holiday table.

Ingredients:

• 1 large butternut squash, peeled, seeded, and cut into 1-inch cubes (about 6-7 cups)
• 3 tbsp olive oil
• 1 tsp ground turmeric
• 1 tsp ground ginger (or 1 tbsp freshly grated)
• 1/2 tsp garlic powder
• 1 tsp fine sea salt
• 1/4 tsp black pepper
• Pinch of cayenne (optional)

Coconut-Lime Scallion Oil:

4. Transfer squash to a platter and spoon the scallion oil over the top.

Garnish with chopped cilantro or toasted coconut flakes. Pair with grilled shrimp or lemongrass chicken. No butternut? Use delicata (no peeling), acorn, or kabocha and adjust roasting time.

Roasting Tips For Whole30 Veggie Perfection

• High heat = caramelization. Aim for 425-450°F to get those crispy edges.
• Don’t crowd the pan. Overcrowding steams instead of roasts; use two pans if needed.
• Dry your veg. Moisture is the enemy of browning—pat them dry after washing.
• Season generously. Salt, acid (vinegar or citrus), and fresh herbs make flavors pop.
• Finish strong. A drizzle of sauce or sprinkle of something crunchy brings it home.

Meal Prep And Pairing Ideas

• Batch roast on Sunday and store in airtight containers for 4 days.
• Pair with proteins: rotisserie chicken (compliant), grilled steak, salmon, shrimp, pork tenderloin, or eggs.
• Add greens: arugula, spinach, shredded kale, or cabbage slaw make easy bowls.
• Sauce roster: compliant mayo-based sauces, tahini dressings, salsa verde, chimichurri with no sugar.

Roasted vegetables can absolutely be the star of your Whole30—bold, bright, and ridiculously satisfying. Pick one to try tonight, then work your way down the list. By the time you hit number seven, you’ll be the person everyone asks for “that amazing roasted veggie recipe,” trust me.
