Recipe Overview
Servings: 4–6
Prep Time: 15 minutes
Cook Time: 1 hour 5 minutes
Total Time: 1 hour 20 minutes
Ingredients
1 medium head cauliflower (about 2 pounds)
2 tablespoons water, for steaming
2 tablespoons Garlic Infused Olive Oil, divided
½ teaspoon kosher salt
¼ teaspoon black pepper
1½ tablespoons 25 Star Dark Balsamic Vinegar
1 small clove garlic, finely grated
½ cup freshly grated Parmigiano-Reggiano
1 tablespoon fresh thyme, chopped, divided
1 teaspoon finely grated lemon zest
Instructions
• Remove the leaves from the cauliflower and trim the bottom of the core so it sits flat and stable.
• Place the trimmed cauliflower in a covered microwave-safe dish with 2 tablespoons water and microwave for 5–6 minutes, or steam on the stovetop for 8–10 minutes, until just starting to soften. This helps the dense core cook through evenly once roasted. Pat the cauliflower dry before continuing.
• Preheat oven to 425°F and line a baking sheet with parchment paper.
• In a small bowl, combine 1 tablespoon Garlic Infused Olive Oil with the finely grated garlic clove. Place the cauliflower core-side down on the baking sheet, drizzle evenly with the garlic-oil mixture, and season with salt and pepper. Roasting the garlic for the full cook develops a sweeter, deeper flavor than adding it only at the end. Keep the cauliflower core-side down for the entire roast — this keeps it stable and lets the domed top brown evenly, and there's no need to flip it.
• Roast for 35–40 minutes. If the exterior begins browning too quickly before the center is tender, loosely tent with foil for part of the roast.
• In a small bowl, whisk together the remaining 1 tablespoon Garlic Infused Olive Oil, 25 Star Dark Balsamic Vinegar, and half of the chopped thyme.
• Remove the cauliflower from the oven and gently separate some of the outer florets with a fork, without disturbing the base. Drizzle the balsamic mixture evenly over the top and let it run down into the openings.
• Return to the oven, still core-side down, and roast for another 15 minutes.
• Gently press the freshly grated Parmigiano-Reggiano onto the cauliflower so it adheres well, forming an even crust.
• Roast an additional 15 minutes, until the cauliflower is deeply golden, the cheese is browned, and a paring knife slides easily into the thickest part of the core with little resistance.
• Remove from the oven and let rest for 5 minutes before slicing into wedges. Spoon any accumulated balsamic glaze from the pan over the top. Finish with the lemon zest and the remaining fresh thyme leaves before serving.
Chef's Tip
Steaming or microwaving the cauliflower briefly before roasting helps the dense core cook through evenly, so you get a tender center without over-browning the exterior — this also lets you roast at a slightly higher temperature for better caramelization. Roasting the garlic in the oil from the start, rather than adding it raw later, gives it time to mellow into a sweeter, deeper flavor. Press the Parmigiano-Reggiano onto the surface rather than sprinkling it loosely, so it forms an even crust that holds together when sliced. There's no need to flip the cauliflower — keeping it core-side down the entire time protects the base and the glaze once it's on. A final touch of lemon zest and fresh thyme after roasting brightens the rich Parmesan and balsamic without tasting overtly lemony.
Flavor Variations
• Add crushed red pepper flakes for subtle heat
• Finish with Black Truffle Extra Virgin Olive Oil for deeper richness
• Swap thyme for rosemary or sage
• Add toasted pine nuts before serving
• Use 25 Star White Balsamic for a lighter finish

Recipe Notes
This dish reheats well and can also be sliced into thick wedges for serving. If the cauliflower begins browning too quickly before the center becomes tender, loosely tent it with foil during the middle portion of roasting. Choose a cauliflower with a flat, sturdy base so it sits securely on the pan throughout roasting. The steaming step can be done a few hours ahead — pat the cauliflower dry and refrigerate, then bring closer to room temperature before roasting.
