Sriracha Onion Boil

Sriracha Onion Boil

This Sriracha Onion Boil combines boiling and roasting for an ultra-tender onion infused with spicy sriracha butter. Boiling softens the onion while oven roasting concentrates flavor and adds light caramelization.
Prep Time 10 minutes
Cook Time 50 minutes
Total Time 1 hour
Servings: 1 onion
Course: Side Dish
Cuisine: American

Ingredients
  

  • 1 large sweet onion about 14–16 oz, peeled and ends trimmed
  • 1 tablespoon unsalted butter
  • 1 tablespoon olive oil
  • 1 tablespoon sriracha adjust to taste
  • salt to taste
  • 1/4 teaspoon garlic powder or smoked paprika optional

Equipment

  • Small Melon Baller or Spoon
  • Medium pot
  • Small Saucepan
  • Aluminum Foil
  • Small Baking Dish

Method
 

  1. Preheat the oven to 375°F (190°C).
  2. Using a small spoon, scoop out the top center of the onion (about one-third of the way down) to create a well.
  3. Place the whole onion in a pot and cover with water. Bring to a boil, then reduce heat and simmer for about 20 minutes, or until slightly tender but still holding its shape. Drain and let cool slightly.
  4. Melt the butter in a small saucepan over medium heat. Remove from heat and stir in olive oil and sriracha.
  5. Place the partially boiled onion on a sheet of aluminum foil. Pour the warm sriracha butter mixture into the well, allowing it to drip between the layers. Season with salt and optional spices.
  6. Seal tightly in aluminum foil and place in a small baking dish.
  7. Bake for 25–30 minutes, until fully tender and infused with flavor.
  8. Optional: Open the foil and broil for 3–5 minutes until the top is slightly charred and caramelized.
  9. Spoon the spicy buttery juices over the onion before serving.

Notes

Boiling first makes the onion extra soft and juicy inside.
Roasting afterward concentrates flavor and adds caramelization.
Adjust sriracha to control heat level.

How to Make Sriracha Onion Boil

Okay, let’s get cooking! This Sriracha Onion Boil comes together so easily, but there are a few key steps that make all the difference. Follow along and you’ll have the most flavorful onion you’ve ever tasted!

Step 1: Prepare the Onion

First, grab your sweet onion and that trusty melon baller. You’ll want to scoop out the top center, going about ⅓ of the way down, think of making a little flavor pocket. Don’t toss those onion bits! I like to chop them finely and sprinkle them back in later for extra texture.

Step 2: Add Flavors

Now for the fun part! Drop that tablespoon of butter right into the onion’s well. Then mix together your sriracha and olive oil, I like to whisk them in a small bowl first so they blend perfectly. Pour this spicy mixture over the onion, letting it drip down into all those layers. Oh, the smell already is incredible!

Storage & Reheating

Here’s the good news, your Sriracha Onion Boil keeps beautifully! Just let it cool completely, then store it in an airtight container in the fridge for 2-3 days.

The flavors actually deepen overnight, bonus!

Sriracha Onion Boil FAQs

Can I use regular onions instead of sweet onions?
You can, but trust me, sweet onions make all the difference! Their natural sugar balances the sriracha’s heat perfectly. Regular yellow onions will work in a pinch, but they’ll be sharper and less caramelized.

How can I make this less spicy?
Easy! Start with just ½ tablespoon of sriracha, or mix it with a little honey or brown sugar to tame the heat. The boiling process mellows the spice too, so don’t judge by the raw mixture’s kick.

Is this Sriracha Onion Boil keto-friendly?
Absolutely! Just skip any sugar additions and you’re golden. The onion’s natural carbs are minimal when portioned right. I’ve served this at keto potlucks and it disappeared fast!

Can I bake instead of boil?
You can, but boiling gives that perfect tender texture. If baking, wrap in foil at 375°F for about 30 minutes. Check often, it dries out easier than the boiled version.
