This silky cauliflower purée transforms a humble vegetable into a luxurious side dish that rivals classic mashed potatoes. The technique creates a velvety texture while maintaining the delicate cauliflower flavor, enhanced with rich butter and aromatic thyme.
I first made this recipe when trying to impress my in-laws with something refined yet approachable. The look of surprise when I revealed it wasn't potato purée but cauliflower was absolutely priceless. Now it appears on our holiday table every year.
Ingredients
- 900g cauliflower florets: Fresh is best as it provides the cleanest flavor and smoothest texture
- 240ml low sodium chicken broth: Using homemade stock elevates this dish tremendously
- 42g unsalted butter, cubed: European style butter with higher fat content creates extra silkiness
- 5g fresh thyme, chopped: Fresh herbs make all the difference compared to dried alternatives
- 5g salt plus more to taste: Diamond Crystal kosher salt is preferred for its clean flavor
- Black pepper to taste: Freshly ground adds subtle heat and complexity
Step-by-Step Instructions
- Start With The Broth Base:
- Add chicken broth and salt to a wide pot and bring to a gentle boil. Using a wide pot rather than a deep one allows more surface area for the cauliflower to cook evenly in the broth, absorbing flavor throughout.
- Steam The Cauliflower:
- Add the cauliflower florets to the boiling broth, then immediately reduce heat to low. Cover the pot and allow the cauliflower to steam for about 20 minutes. The florets should be very tender when pierced with a fork but not completely falling apart. This gentle cooking method preserves the delicate flavor better than aggressive boiling.
- Transfer And Prepare For Blending:
- Using a slotted spoon, carefully transfer the cooked cauliflower to a food processor. Work in batches if necessary to avoid overcrowding. Reserve the cooking liquid as you will need some for the next step.
- Create The Butter Emulsion:
- Return to your pot with the remaining hot cooking liquid. Add the cubed butter to about 3 tablespoons of the hot broth and whisk continuously until the butter is completely melted and incorporated. This creates a simple emulsion that will give the purée its luxurious mouthfeel.
- Blend To Perfection:
- Pour the butter mixture into the food processor with the cauliflower. Add the chopped fresh thyme, a few grinds of black pepper, and additional salt to taste. Process until completely smooth, stopping occasionally to scrape down the sides. For an ultra silky texture, blend for at least 2 minutes.
- Adjust Consistency:
- If the purée seems too thick, add small amounts of the warm cooking broth until you reach your desired consistency. Remember that the purée will thicken slightly as it cools, so aim for a slightly looser texture than your final goal.
- Serve With Care:
- Transfer to a warmed serving dish and serve immediately for best results. A small swirl of olive oil or an extra pat of butter on top adds a beautiful finishing touch.

The chicken broth is truly the secret ingredient in this recipe. I once tried making it with just water and the difference was remarkable. The broth infuses the cauliflower with savory depth that transforms this from a simple vegetable side into something company-worthy.
Perfect Temperature Control
The key to serving this purée at its best is temperature management. Unlike mashed potatoes which can hold up to piping hot temperatures, cauliflower purée actually tastes better when served warm rather than hot. Excessive heat can bring out sulfurous compounds in the cauliflower family. Aim for a pleasant warm temperature where the butter is fully melted but not steaming hot.
Make-Ahead Options
This cauliflower purée can be prepared up to two days in advance and stored in an airtight container in the refrigerator. To reheat, place in a saucepan over medium-low heat with a splash of broth or milk, stirring frequently until warmed through. Alternatively, microwave in 30-second intervals, stirring between each, until reaching your desired temperature. The texture remains remarkably consistent even after refrigeration.
Flavor Variations
While this classic version with thyme complements most main dishes beautifully, the cauliflower purée also serves as an excellent canvas for other flavor profiles. Try adding roasted garlic for depth, a pinch of curry powder for warmth, or fold in some Parmesan cheese at the end for a nutty finish. Each variation opens up new pairing possibilities with your favorite proteins.
