Ingredients You’ll Need
Each ingredient plays a role in layering flavor—and I want you to be confident grabbing what you need. The fresh herbs are especially key to building that aromatic gravy you’ll fall in love with. When shopping, try to find a firm, white head of cauliflower and fresh, fragrant herbs for the best results.
- Cauliflower: Choose a firm head with tight white florets for roasting perfection.
- Melted Butter: Adds richness and helps the cauliflower caramelize beautifully.
- Kosher Salt: Essential for seasoning to bring out natural flavors evenly.
- Black Pepper: Freshly ground gives the best gentle heat and aroma.
- Whole Garlic Cloves: Roasting the garlic whole mellows its sharpness into a sweet, buttery flavor.
- Fresh Sage: Provides an earthy and slightly peppery note in both the roast and gravy.
- Fresh Thyme: Its lemony undertones make all the herbs pop.
- Fresh Rosemary: Piney and fragrant—just enough to deepen the herb blend.
- Onion (for gravy): Adds sweetness and body to the sauce.
- Cremini Mushrooms: Boost the gravy’s umami and earthiness.
- All-purpose Flour: Thickens the gravy to a silky texture.
- Low-sodium Vegetable Broth: Keeps the gravy light but flavorful, so you can control seasoning.
Variations
I love how flexible this recipe is. You can keep it classic or tweak it to match your family’s tastes or dietary needs. Don’t hesitate to play around with the herbs or even add a little heat if that’s your jam—cooking is all about making it your own.
- Vegan Variation: Swap the butter with olive oil or vegan butter and use a vegetable broth-based gravy without any butter—still incredibly tasty!
- Spice it Up: I once added a pinch of smoked paprika and red pepper flakes to the butter rub—it gave a lovely smoky warmth.
- Cheesy Twist: Sometimes I sprinkle a bit of grated Parmesan over the cauliflower near the end of roasting for a golden crust my family goes crazy for.
- Herb Swaps: If you don’t have fresh rosemary, dried works in a pinch, or experiment with fresh tarragon or marjoram for a different spin.
How to Make Thanksgiving Roasted Cauliflower with Herb Gravy Recipe
Step 1: Prep and Season Your Cauliflower
Start by preheating your oven to 450°F. Place the whole cauliflower head in a large oven-safe skillet—this is going to be the star. Rub it all over with 2 tablespoons of melted butter. Don’t skimp on this step because it ensures a perfect golden roast and adds silky richness. Season generously with kosher salt and freshly ground black pepper. Tuck the whole garlic cloves and fresh herb sprigs (sage, thyme, and rosemary) around the cauliflower—they’ll infuse amazing fragrance as everything roasts together.
Step 2: Roast Slowly Until Tender
Pop the skillet into the oven and roast for about 1 hour to 1 hour and 30 minutes. Midway through, brush the cauliflower with the remaining 2 tablespoons of melted butter—trust me, this keeps it moist and encourages caramelization. You’ll know it’s done when you can easily pierce the center with a paring knife and it feels tender but still holds its shape. That slight char on the edges is just what you want.
Step 3: Make the Herb Gravy
While your cauliflower is roasting, prepare the gravy. Melt 4 tablespoons of butter in a small saucepan over medium heat. Add finely chopped onion and sauté until soft, about 5 minutes. Then stir in finely chopped cremini mushrooms and the fresh chopped herbs (sage, rosemary, thyme), seasoning lightly with salt and pepper. Cook this mixture until the mushrooms turn golden, about 4 minutes. Take 1 or 2 of the roasted garlic cloves (skins removed) and mash them into the pan—this adds a subtle roasted sweetness.
Sprinkle in the flour and cook for another minute to eliminate any raw taste. Slowly whisk in 2 cups of low-sodium vegetable broth, bringing the gravy to a boil. Lower the heat and let it simmer until it thickens, about 5 minutes. Add more broth if you want a thinner consistency.
Step 4: Serve and Enjoy
When the cauliflower is perfectly roasted and your gravy is ready, plate it up! I usually slice the cauliflower into wedges for easier serving and then drizzle a generous amount of that herb gravy over the top. The combo of texture and flavor is just incredible.
Pro Tips for Making Thanksgiving Roasted Cauliflower with Herb Gravy Recipe
- Butter Basting: Brushing the cauliflower halfway through roasting keeps it moist and encourages a beautiful caramelized crust.
- Garlic Magic: Roasting whole garlic cloves with the cauliflower softens their bite and brings a subtle sweetness to both the roast and the gravy.
- Fresh Herbs Matter: Using fresh instead of dried herbs in the gravy makes a world of difference for flavor depth and aroma.
- Check Tenderness Often: Don’t hesitate to pierce the cauliflower with a sharp knife to test doneness after one hour so you don’t overcook it.
How to Serve Thanksgiving Roasted Cauliflower with Herb Gravy Recipe
Garnishes
I like to sprinkle freshly chopped parsley or a little cracked black pepper right before serving for a fresh pop of color and zing. Sometimes a few extra rosemary needles or a drizzle of browned butter takes the presentation up a notch. These simple touches make it feel extra special.
Side Dishes
This roasted cauliflower with herb gravy pairs beautifully with classic mashed potatoes or a wild rice pilaf. For a lighter option, I often serve it alongside a crunchy winter salad with citrus vinaigrette. It’s also fantastic with roasted Brussels sprouts or sweet potatoes—your plate will feel colorful and balanced.
Creative Ways to Present
One Thanksgiving, I placed the whole roasted cauliflower on a large wooden board surrounded by piles of fresh herbs and edible flowers—guests loved its rustic charm. Another time, I cut the cauliflower into thick steaks and arranged them overlapping on a platter, drizzled the herb gravy artistically, and topped with toasted pine nuts for crunch. Presentation can be so fun when you have a stunning main like this!
Make Ahead and Storage
Storing Leftovers
I store leftover roasted cauliflower and herb gravy separately in airtight containers in the fridge. This method helps keep the cauliflower from getting soggy overnight, so when I reheat, it still has great texture the next day.
Freezing
You can freeze the leftover gravy in a sealed container or ice cube trays for quick portions later. I wouldn’t recommend freezing the roasted cauliflower itself because it loses some of its roasted texture after thawing—but the gravy freezes beautifully.
Reheating
To reheat, gently warm the cauliflower in a 350°F oven to regain some crispness (about 10-15 minutes). Heat the gravy on the stovetop over low-medium heat, stirring occasionally, until smooth and hot. This keeps the flavors fresh and the textures just right.
FAQs
-
Can I use dried herbs instead of fresh for the herb gravy?
Yes, you can substitute dried herbs if fresh aren’t available, but reduce the amount to about one-third since dried herbs are more concentrated. Adding them early in the cooking process helps release their flavors.
-
How do I know when the cauliflower is fully cooked?
After about an hour, insert a sharp paring knife or skewer into the center of the cauliflower. It should slide in easily without resistance but the vegetable should still hold its shape. If it feels too firm, give it more time roasting.
-
Can this recipe be doubled for a larger crowd?
Absolutely! If you have a bigger oven-safe pan or roasting tray, you can roast two heads of cauliflower at once. Just keep an eye on the roasting time—it may need a few extra minutes to ensure even cooking.
-
Is the herb gravy suitable for vegans?
With a few swaps, yes! Replace butter with vegan butter or olive oil, and use vegetable broth. Omit any dairy-based ingredients and you’ve got a delicious vegan-friendly gravy.
-
What if I don’t have an oven-safe skillet?
No worries! You can roast the cauliflower on a baking sheet or in a roasting pan. Just turn the cauliflower carefully halfway through and use a brush to apply the melted butter as usual.
Final Thoughts
This Thanksgiving Roasted Cauliflower with Herb Gravy Recipe has become a treasured dish in my home. I love how it feels both fancy and down-to-earth, bringing my family together around a warm, flavorful plate. If you’ve ever thought roasted cauliflower was just a sidekick, this recipe will change your mind. Give it a try, and I promise you’ll be asked to make it again — whether it’s November or any night when you want something cozy and impressive.

Ingredients
Main Ingredients
- 1 large head of cauliflower
- 4 Tbsp. melted butter, divided
- Kosher salt, to taste
- Freshly ground black pepper, to taste
- 4 whole cloves garlic (skin-on)
- 4 leaves fresh sage
- 4 sprigs fresh thyme
- 4 sprigs fresh rosemary
Gravy Ingredients
- 4 Tbsp. butter
- 1/2 onion, finely chopped
- 4 oz. cremini mushrooms, finely chopped
- 1 tsp. freshly chopped sage
- 1 tsp. freshly chopped rosemary
- 1 tsp. freshly chopped thyme
- 3 Tbsp. all-purpose flour
- 2 to 4 cups low-sodium vegetable broth
Instructions
- Prepare and Season Cauliflower: Preheat your oven to 450°F. Place the whole cauliflower in a large oven-safe skillet, then rub it all over with 2 tablespoons of melted butter. Season generously with kosher salt and freshly ground black pepper. Arrange the skin-on garlic cloves and fresh herb leaves and sprigs (sage, thyme, rosemary) around the cauliflower to infuse it with their aromatic flavors during roasting.
- Roast Cauliflower: Bake the cauliflower in the preheated oven until tender and slightly charred, roughly between 1 hour to 1 hour and 30 minutes. Halfway through roasting, brush the cauliflower with the remaining 2 tablespoons of melted butter to keep it moist and flavorful. Test doneness by piercing the cauliflower with a paring knife to ensure tenderness.
- Make Gravy Base: While the cauliflower roasts, melt 4 tablespoons of butter in a small saucepan over medium heat. Add the finely chopped onion and cook, stirring occasionally, until softened, about 5 minutes. Stir in the chopped cremini mushrooms and fresh herbs (sage, rosemary, thyme). Season with salt and pepper, then cook the mushroom mixture until the mushrooms become soft and golden, about 4 minutes.
- Add Roasted Garlic and Flour: Remove 1 or 2 cloves of the roasted garlic from the cauliflower, discard the skins, and mash the cloves with a wooden spoon into the mushroom mixture. Stir in the flour and cook for 1 minute to eliminate the raw flour taste, creating a flavorful roux that will thicken the gravy.
- Simmer Gravy: Gradually whisk in 2 cups of low-sodium vegetable broth, bringing the mixture to a boil. Reduce the heat to low and let the gravy simmer until it thickens to your desired consistency, about 5 minutes. If needed, add more vegetable broth (up to 2 additional cups) to thin the gravy or adjust thickness.
- Serve: Plate the roasted cauliflower and generously spoon the warm mushroom herb gravy over it. Serve immediately as a hearty vegetarian centerpiece for your Thanksgiving meal.
Notes
- Use a paring knife to check the cauliflower’s tenderness during roasting; it should pierce easily but the head should hold together.
- For a vegan version, substitute butter with a plant-based alternative and ensure the vegetable broth is vegan.
- The garlic cloves roast inside the skin to mellow their flavor; removing and mashing them into the gravy adds a subtle roasted garlic depth.
- Gravy thickness can be adjusted by adding more or less vegetable broth according to preference.
- Fresh herbs are essential for authentic flavor; however, dried herbs can be used in a pinch at one-third the quantity.
