Recipe Ingredients
Gather these ingredients for a simple pan of roasted cauliflower and carrots:
Ingredient Notes & Substitutions
The core ingredients are cauliflower and carrots, while the rest are flexible depending on taste and pantry items:
- Onion: Adds sweetness and depth when roasted; omit if you prefer.
- Oil: Olive oil is ideal for flavor, but avocado or another neutral oil will work.
- Chili powder: Use chili seasoning (a spice blend) rather than pure ground chiles; it adds mild warmth and complexity.
- Spices: Garlic and onion powder, salt, and black pepper create a simple, balanced seasoning. Red pepper flakes can be added if you like more heat.
- Citrus: A squeeze of lime (or lemon) after roasting brightens the dish and ties the flavors together; it’s optional but recommended.
How to Make Roasted Cauliflower and Carrots
Below are the essential steps—full measurements and details are in the printable recipe card further down.
Step 1: Cut the cauliflower into even florets, slice the carrots about 1/4-inch thick, and halve and slice the onion. Place the vegetables on a lined baking sheet, drizzle with oil, and sprinkle with the spice mix.
Step 2: Toss the vegetables until evenly coated, then roast at 400°F for 25–30 minutes, stirring once halfway through, until a fork just pierces the largest pieces. Finish with a squeeze of lime if desired.
Tips & Storage
Jami’s Tip
To roast by about 25 minutes, cut cauliflower into smaller, even florets and halve any large pieces. Test doneness with a fork—aim for tender but still slightly firm pieces rather than very soft.
- Make Ahead: Prepare 2–3 days ahead and refrigerate. Reheat gently in a 350°F oven for 5–10 minutes.
- Storage: Store in an airtight container in the fridge for up to a week—great for meal prep alongside grilled proteins.
- Reheating: Microwave for about a minute, stirring once, or warm on a sheet pan in a toaster oven or regular oven for 5–10 minutes.
- Freezing: Roasted vegetables generally freeze well if slightly under-roasted (about 20–25 minutes) so they stay firmer after thawing. Thaw before reheating.
