Ingredients for Thomas Keller’s Roasted Zucchini

To create masterpiece-level flavor, Thomas Keller’s Roasted Zucchini relies on a few select, high-quality ingredients. Here’s what you’ll need:

• 2 large zucchini or summer squash: Choose firm, glossy-skinned zucchini or summer squash around 8-10 inches long. The recipe works beautifully with either vegetable.
• 1 teaspoon sea salt: Essential for draining excess moisture and enhancing the natural sweetness of the zucchini.
• 1 tablespoon neutral cooking oil: Avocado oil or grapeseed oil are ideal for their high smoke points and neutral flavor, allowing the miso glaze to shine.
• 1 tablespoon miso: Opt for white or yellow miso paste for a mild, slightly sweet umami flavor that complements the zucchini perfectly.
• 2 teaspoons maple syrup: Offers subtle caramel notes and balances the savoriness of miso with gentle sweetness.
• 2 teaspoons sake: Provides just a hint of depth and complexity. If unavailable, dry white wine or rice vinegar can substitute (see Substitutions below).
• Toasted sesame seeds and sliced scallions: These garnishes add toasty crunch and a burst of fresh green color, elevating both the appearance and taste of the finished dish.

Each ingredient in Thomas Keller’s Roasted Zucchini is purposefully chosen to maximize flavor and elevate your dinner table with minimal fuss.

Necessary Tools

While Thomas Keller’s Roasted Zucchini looks sophisticated, the kitchen tools required are wonderfully straightforward:

• A sharp chef’s knife or santoku: Crucial for slicing zucchini smoothly and cleanly.
• A small spoon or paring knife: For scoring the zucchini’s cut side into a crosshatch pattern (this helps the flavors penetrate deeply).
• Cast iron skillet: Delivers the signature deep sear and retains heat beautifully for an even roast. If unavailable, a heavy ovenproof skillet works as well.
• A sturdy spatula: For flipping and handling the zucchini.
• A small bowl and brush: Handy for mixing and applying the miso-maple glaze.
• Oven mitts or heat-safe gloves: Safety first! Especially important when moving the hot skillet from stove to oven and then to broiler.

Keep these simple but essential tools on hand and you’ll be ready to achieve perfect results with Thomas Keller’s Roasted Zucchini.

Ingredient Additions & Substitutions

One of the joys of Thomas Keller’s Roasted Zucchini is its flexibility. The original ingredients shine, but creativity is always welcome in the kitchen! Here’s how to riff on the basics:

• Zucchini/Summer Squash: While classic green zucchini is ideal, yellow summer squash or even pattypan squash can be swapped in seamlessly. For a larger crowd, try using a combination for color contrast and a subtle flavor twist.
• Miso Paste: White miso is mildest, but a touch of red or chickpea miso adds deeper savory notes. For a soy-free version, use chickpea miso or tahini for a different, nutty depth.
• Maple Syrup: Agave nectar or honey (if not vegan) are both solid stand-ins. Brown rice syrup works too, lending a slightly earthier finish.
• Sake: No sake? Substitute with a splash of dry white wine, mirin, or even a tiny amount of rice vinegar diluted with water. Each will add nuanced acidity and body to the glaze.
• Sesame Seeds/Scallions: Try black sesame seeds for dramatic color, or swap scallions for thinly sliced chives, cilantro, or crispy shallots for a new spin.
• Add-Ins: For extra heat, sprinkle on crushed red pepper or thinly sliced fresh chili after roasting. Love garlic? Rub a clove over the hot zucchini or mix a bit of grated garlic into the glaze.

Whether you need to make Thomas Keller’s Roasted Zucchini vegan, gluten-free, or just want to try unexpected flavor pairings, these suggestions ensure the recipe fits your tastes and dietary needs.

How to Make Thomas Keller’s Roasted Zucchini

Thomas Keller’s Roasted Zucchini is a masterclass in transforming ordinary vegetables into extraordinary fare. The combination of crosshatching, searing, roasting, and glazing produces unmatched flavor and texture. Follow these expert steps for restaurant-quality results at home.

Step 1: Prep the Zucchini

Start by washing and drying your zucchini thoroughly. Slice each one lengthwise to create two long, even halves. Using a sharp knife, score the exposed cut face of each half in a shallow crosshatch pattern—be careful not to pierce through the skin. This elegant trick helps the salt draw out moisture and lets the fabulous miso glaze soak in later.

Step 2: Salt and Drain

Generously sprinkle the cut sides of the zucchini with sea salt. Lay them cut-side down on a paper towel or plate and let sit for 15 to 20 minutes. This step pulls out excess water, ensuring the zucchini becomes meltingly soft with a deep, golden sear—not soggy.

Step 3: Rinse and Dry

After draining, rinse the zucchini halves to remove any surface salt. Pat them completely dry with a clean towel—removing all moisture is crucial for the best sear.

Step 4: Sear in Skillet

Preheat your oven to 400°F (205°C). Heat the neutral oil in your cast iron skillet over medium-high heat. Once the oil shimmers, place the zucchini halves cut-side down and press gently for full contact. Sear, undisturbed, for about 7 minutes until deep golden brown.

Step 5: Oven Roast

Transfer the skillet (be careful, it’s hot!) to your preheated oven. Roast the zucchini for 15 minutes. This crucial step ensures the flesh turns silky and deeply flavorful, while the skin remains intact and beautifully roasted.

Step 6: Miso Glaze

While the zucchini roasts, whisk together the miso paste, maple syrup, and sake in a small bowl. Once the roasting time is up, remove the skillet from the oven. Brush the miso-miso glaze generously over the scored cut sides of the zucchini.

Step 7: Broil for Finish

Slip the skillet under your broiler for about 3 minutes. Watch closely—the glaze will bubble and caramelize, transforming into a shiny, flavor-packed coating without burning.

Step 8: Garnish & Serve

Remove from the oven and immediately scatter thinly sliced scallions and toasted sesame seeds across the zucchini. Serve right in the skillet or transfer carefully to a warmed platter for extra elegance. Congratulations—you’ve just created Thomas Keller’s Roasted Zucchini!

How to Serve Thomas Keller’s Roasted Zucchini

Presentation is part of the magic with this recipe. Serve Thomas Keller’s Roasted Zucchini hot, straight from the skillet for rustic charm, or on a sleek white platter, garnished with extra sesame seeds and scallions for a sophisticated look. This dish shines alongside roasted chicken, grilled fish, or as a star at a vegetarian feast. It also pairs beautifully with steamed jasmine rice or a fluffy quinoa pilaf for a balanced, plant-powered supper. Don’t forget a squeeze of fresh lemon or a drizzle of chili oil just before serving to brighten flavors even more. No matter the occasion, this zucchini dish is destined to steal the show.

Pro Tips & Tricks

• For super crisp edges, don’t overcrowd the skillet. Work in batches if necessary so the zucchini gets golden and caramelized, not steamed.
• Score the zucchini deeply (but not all the way through) to maximize glaze absorption.
• Always preheat the skillet and make sure the oil shimmers—this allows for that restaurant-worthy sear.
• Let the salted zucchini drain fully on paper towels to guarantee a tender, custardy texture inside.
• Make the glaze ahead of time and keep refrigerated for up to 4 days—it tastes phenomenal as a sauce for other roasted vegetables or even tofu!
• To make Thomas Keller’s Roasted Zucchini a main course, serve over a bed of herbed grains or pair with a warm lentil salad and a poached egg.
• Garnishing just before serving preserves the vibrant color and crunch of scallions and sesame seeds.

Storage Instructions

Thomas Keller’s Roasted Zucchini is best enjoyed hot and fresh, straight from the oven. However, leftovers keep well when handled properly. Store any uneaten zucchini in an airtight container in the refrigerator for up to 3 days. To reheat, arrange slices cut-side up on a baking sheet and warm in a 350°F oven for 8-10 minutes, or until heated through and glossy again. Avoid microwaving, as it can make the zucchini limp. Glaze may thicken in the fridge—this is normal and still delicious when reheated. Bring leftover portions to room temperature for 15 minutes before reheating to ensure an even result.
