Can I make the sriracha sauce ahead of time?
Yes. Mix the mayo, sriracha, vinegar, sugar, and garlic powder up to 2 days ahead and refrigerate. Toss with roasted Brussels sprouts just before serving.
How do I know when the Brussels sprouts are crispy enough?
Roast at high heat until the cut sides are deeply browned and the outer leaves are caramelized and slightly charred, about 20–25 minutes.
Can I adjust the spice level?
Yes. Reduce sriracha to 1.5 tsp for mild heat or increase to 1.5 tbsp for extra spice. Taste the sauce before tossing.
Can I use a different oil for roasting?
Avocado oil, vegetable oil, or canola oil work equally well. Avoid extra-virgin olive oil, which may burn at high roasting temperatures.
Is this recipe gluten-free?
Yes, all ingredients are naturally gluten-free. Verify that your sriracha brand is certified gluten-free if serving those with celiac disease.
