- ¼ cup olive oil (divided): Essential for roasting and creating that beautiful golden finish.
- 4-6 thyme sprigs: Fresh thyme infuses a subtle herby note complementing both cauliflower and chimichurri.

How to Make Roasted Cauliflower with Chimichurri Sauce Recipe
Step 1: Prepare Your Cauliflower and Vegetables
Start by cutting your cauliflower head into evenly sized florets to ensure uniform roasting. Slice the sweet onion thickly so it roasts tender but retains a bit of bite. Toss the cauliflower, onion slices, and whole garlic cloves with half of the olive oil, kosher salt, black pepper, and the thyme sprigs. The olive oil will help everything caramelize beautifully while seasoning enhances flavor. Be generous with tossing to coat all pieces evenly.
Step 2: Roast Until Golden and Tender
Spread the cauliflower, onion, and garlic in a single layer on a baking sheet. Roast in a preheated oven at 425°F (220°C) for about 35-40 minutes. Check halfway through and give the veggies a gentle stir to promote even browning. You’ll know they’re done when the cauliflower florets are tender inside with beautifully crisped edges and the garlic has softened to buttery sweetness.
Step 3: Finish with Crushed Red Pepper and Olive Oil
Once roasted, remove the thyme sprigs and sprinkle the crushed red pepper over the hot veggies. Drizzle the remaining olive oil for an extra luscious finish. This final touch balances the dish with a subtle heat and silky richness that elevates the overall flavor.
Step 4: Drizzle with Chimichurri Sauce
The pièce de résistance of the Roasted Cauliflower with Chimichurri Sauce Recipe is, of course, the fresh chimichurri. Generously spoon the sauce over the warm cauliflower and vegetables. The bright herbs, garlic, and vinegar notes in the chimichurri add a fresh, zesty contrast that brings this dish alive.
How to Serve Roasted Cauliflower with Chimichurri Sauce Recipe

Garnishes
For an eye-catching finish, sprinkle chopped fresh parsley or cilantro on top, or add a few torn basil leaves. A dusting of toasted pine nuts or slivered almonds adds texture and a nutty boost. Don’t be shy with a few extra chili flakes if you like a little more heat to complement the herbs.
Side Dishes
This roasted cauliflower pairs beautifully with a variety of sides. Try it alongside warm quinoa, fluffy couscous, or creamy mashed potatoes to soak up every last bit of chimichurri. It’s equally delicious served with grilled meats or roasted chicken for a complete meal.
Creative Ways to Present
For a stunning appetizer, serve individual portions on small plates, drizzled elegantly with chimichurri and garnished with microgreens. You could also toss the roasted cauliflower with cooked pasta and additional chimichurri for an effortlessly flavorful vegetarian main course. The versatility makes this recipe a perfect candidate for entertaining or casual weeknight dinners.
Make Ahead and Storage
Storing Leftovers
Leftover roasted cauliflower with chimichurri sauce keeps well in an airtight container in the refrigerator for up to 3 days. Store the sauce separately if possible to keep the cauliflower from becoming soggy, then drizzle before serving.
Freezing
While the roasted cauliflower itself freezes well, chimichurri sauce is best enjoyed fresh. You can freeze the cauliflower in a sealed container or bag for up to 1 month, but fresh chimichurri will always bring more vibrancy and texture.
Reheating
To reheat, warm the roasted cauliflower gently in a preheated oven at 350°F (175°C) until heated through and crisped slightly again. Avoid microwaving to preserve the texture, then add fresh chimichurri sauce right before serving for that burst of fresh flavor.
FAQs
Can I make my own chimichurri sauce for this recipe?
Absolutely! Homemade chimichurri made with fresh parsley, garlic, red wine vinegar, olive oil, and spices will elevate this recipe beautifully. It’s easy to make and tastes incredibly fresh, but store-bought versions work well too for convenience.
What if I don’t have fresh thyme? Can I substitute dried?
Yes, dried thyme can be used as a substitute. Use about one-third of the amount since dried herbs are more concentrated. The flavor won’t be quite as vibrant, but it will still nicely complement the roasted vegetables.
Is this recipe vegan and gluten-free?
Yes, the Roasted Cauliflower with Chimichurri Sauce Recipe is naturally vegan and gluten-free, making it a fantastic option for many dietary preferences.
Can I add other vegetables to this dish?
Feel free to add sturdier vegetables like carrots, bell peppers, or zucchini. Just be mindful of cooking times as some veggies roast faster or slower than cauliflower, so adjust accordingly to avoid overcooking.
How spicy is the crushed red pepper in this recipe?
The crushed red pepper adds a mild heat that nicely balances the herbaceous chimichurri and roasted cauliflower. If you prefer less spice, reduce or omit it; conversely, add more if you love a little extra kick.
Final Thoughts
I can’t recommend the Roasted Cauliflower with Chimichurri Sauce Recipe enough if you’re craving something easy, healthy, and full of vibrant flavor. It’s a foolproof way to transform simple ingredients into a truly memorable dish that brings brightness and comfort to any meal.
