Why You’ll Love Spicy Roasted Cauliflower and Butternut Squash
Delicious Details

- Skill Level: Easy
If you are asking me what’s on my dinner menu, at least three or four nights of the week you can bet that one of the side dishes will be some sort of roasted vegetables. We certainly love basic roasted cauliflower and simple roasted butternut squash. Just olive oil, salt, pepper, and a nice high temperature in the oven can bring the best out of pretty much and vegetables. However, all you have to do is open your spice cabinet to add a whole new dimension of flavor to those veggies. Here’s why we can’t get enough.
- Great flavor. The smoky and spicy combination of chili powder and cumin is one of my favorite pairings, especially when combined with the fresh and tangy flavor you get from adding a squeeze of lime juice.
- Perfectly caramelized. Roasting at a high temperature means the cauliflower and butternut squash turn out nice and tender with crispy edges.
- The right amount of heat. You can definitely add it to the menu when the kids are begging for Ground Beef Tacos or Chicken Tostadas because it just has a hint of heat, and you can always use less chili powder. Of course, if you want your mouth on fire, you can also add more or try using one made with chipotles or habaneros.
- Allergy-friendly. This easy side dish doesn’t have any gluten, dairy, nuts, or eggs. You can even use all cauliflower or replace the squash with another vegetable for a low carb option.
Ingredients for Chili Lime Cauliflower and Butternut Squash
Besides your veggies, you only need a few simple ingredients to make this spicy side dish. Here is a quick overview of what you’ll need. Be sure to scroll to the recipe card for the full amounts and detailed instructions.
- Butternut squash: A medium one that’s about 2-3 pounds.
- Cauliflower: One head that is also around 2-3 pounds.
- Olive oil: For coating those veggies.
- Lime juice: Fresh is best.
- Salt and pepper
- Chili powder: A basic chili powder is fine, but you can always add more heat or smoke with an ancho, chipotle
- Cumin: Adds a nice, smoky flavor but if you aren’t a fan, you can skip it.
How to Roast Vegetables with Chili and Lime
Let’s get ready to roast the cauliflower and butternut squash. Preheat the oven to 450°F, prepare your baking sheet, and get started.
- Wash and cut the squash. First, wash and dry the outside of the butternut squash. Slice off the top and bottom, and use a heavy-duty peeler to peel off the thick skin. Cut the top part from the bottom bulb portion, cut the bulb in half, and scrape out the seeds with a spoon. Then cut the entire squash into about 1-inch pieces.
- Prep the cauliflower. Cut the thick leaves off of the bottom of the cauliflower, rinse it well, and dry it on a kitchen towel. Then using a small, sharp knife, such as a paring knife or kitchen utility knife, cut the cauliflower into medium-sized florets. The smaller you make them, the crispier they will get.
- Toss in seasonings. Add the vegetables to a large bowl or right on the prepared sheet pan. Drizzle them with olive oil and lime juice, and sprinkle with salt, chili powder, cumin, and black pepper. Toss everything to coat evenly.
- Roast the veggies. Place the pan in the preheated oven for 30-40 minutes, flipping once about halfway through. At 30 minutes, they will be crisp-tender and starting to brown. If you like them a bit softer and more caramelized (maybe with even a bit of delicious char), go for the full 40 minutes.
Tips for the Best Spicy Roasted Cauliflower and Butternut Squash
- Use the right knife. Butternut squash can be hard to cut, so I recommend using a large, sharp kitchen knife. A smaller utility or paring knife is easiest for cutting the florest off of the cauliflower.
- Have good pans. My favorite baking sheets are the ones from Nordicware. They are thick so they don’t warp, but not too heavy. And with just a bit of oil or cooking spray or a sheet of parchment paper, sticking is never and issue and cleanup is a breeze. I prefer the caramelization you get from roasting right on the pan, which is why I love that these pans clean up easily.
- Prep ahead. The vegetables can be chopped and even be tossed in the seasonings and kept refrigerated to roast right before serving. The roasted veggies can also be kept in the refrigerator (see below for storage instructions), but they won’t have the same texture as when you enjoy them fresh out of the oven and they will be a little softer.
Storing and Reheating Leftovers
Leftover Spicy Roasted Cauliflower and Butternut Squash can be stored in a covered container in the refrigerator for up to 2 or 3 days. You can reheat them in the microwave, though they will get soft. Popping it back in the oven for 10-15 minutes will restore some of the crisp texture.
Can you freeze leftover roasted cauliflower and butternut squash?
You can technically freeze roasted vegetables. Just be sure to seal them tightly in an airtight container or plastic freezer storage bag and they will keep for up to 2 months. That being said, they may be a little mushy once thawed. You can try to restore some of the crispy edges by reheating them in a hot oven or even in an air fryer.
