Ingredients You’ll Need

Let’s break down what goes into making this flavor-packed cauliflower:

1/2 cup smooth, creamy peanut butter – The base of the rich, nutty sauce.
1/4 cup liquid aminos or gluten-free soy sauce – Brings that umami punch.

1/4 cup honey or agave (or sugar-free honey) – Adds just the right touch of sweetness.
6 tbsp mild-tasting oil – Think avocado, grapeseed, or olive oil.
4 tbsp toasted sesame oil – For that deep, nutty, signature Asian flavor.

2 tbsp fresh grated ginger – Adds brightness and zing.
2-4 tsp sriracha – Adjust to your spice tolerance.
1 whole head of cauliflower – Choose a firm, medium-to-large head.

Optional Garnishes:
- 2 tbsp chopped green onions
- 2 tbsp chopped salted peanuts
- Extra sriracha for drizzling

Step-by-Step Instructions

1. Preheat and Prep

Preheat your oven to 400°F (200°C). While the oven warms up, prepare your sauce by whisking together peanut butter, soy sauce, honey/agave, oils, ginger, and sriracha in a bowl. Mix until it becomes smooth and pourable.

2. Prepare the Cauliflower

Remove the green leaves and trim the stem of the cauliflower so it sits flat in your baking pan. This not only helps with even cooking but also enhances presentation.

3. Brush with Sauce

Place the cauliflower in a cast iron skillet or oven-safe baking dish. Brush it generously with the sauce, making sure to coat all sides. Cover with foil.

4. Bake Until Tender

Roast the covered cauliflower for 40–50 minutes. It should be fork-tender—easily pierced with a knife.

5. Broil and Glaze

Remove the foil. Brush on another layer of sauce, then broil for 2–4 minutes. Repeat this process two more times: brush, broil, repeat. This builds a rich, thick glaze that caramelizes beautifully.

6. Final Touches

After the final broil, give it one more brush of sauce and top with green onions, chopped peanuts, and a drizzle of sriracha if you like extra heat.

Recipe Tips and Tricks

Short on time? Steam the cauliflower head for 5–7 minutes before roasting to reduce oven time.
Low-sugar version? Use sugar-free honey or a keto-friendly sweetener like monk fruit syrup.

Nut-free version? Sub sunflower seed butter or tahini for peanut butter.
Extra crispy edges? After the final broil, let the cauliflower sit under the broiler for an extra minute or two—just watch it carefully to prevent burning.

Serving Suggestions

Pair your Thai Peanut Roasted Cauliflower with:

Steamed jasmine or brown rice for a satisfying meal
Chilled cucumber salad with lime and cilantro for contrast

Thai iced tea or a crisp dry white wine like Riesling or Sauvignon Blanc
Crunchy slaw with lime vinaigrette as a refreshing side

This dish is also a fantastic meatless Monday star or holiday main course for plant-forward celebrations.

How to Store Leftovers

This cauliflower stores beautifully and reheats well. To store:

Refrigerate: Place leftovers in an airtight container for up to 4 days.
Reheat: Warm in the oven at 350°F (175°C) for 10–15 minutes or microwave individual servings.
Pro Tip: For a quick lunch, chop up leftover cauliflower and toss with cooked rice or noodles and fresh herbs.

FAQs

Can I make this ahead of time?

Yes! You can prep the sauce and cauliflower a day in advance. Roast the cauliflower as directed, then cool and refrigerate. When ready to serve, reheat and apply the final broil and sauce layers.

Is this recipe vegan?

It can be! Just use agave syrup or maple syrup instead of honey.

What’s a good substitute for sriracha?

Try sambal oelek, chili garlic sauce, or a few dashes of hot sauce of your choice.

Can I use frozen cauliflower?

This recipe works best with fresh whole cauliflower for structure and roasting. Frozen florets are better for stir-fries or soups.

Can I turn this into a bowl meal?

Absolutely. Roast the cauliflower, then chop and serve over rice, quinoa, or noodles with extra sauce and toppings.
