Step 1

Turn on oven to high broil. (If you're oven has a broil temperature setting, set to 525 degrees). Line baking sheet with foil.

Step 2

Peel off tomatillo outer shells and stems of serrano peppers.

Step 3

Add tomatillos, peppers, and garlic to pan and broil until browned on tops and then rotate veggies and brown other side. About 6-7 minutes first side, 4 minutes second side.

Step 4

Use a food processor (or blender) to blend all roasted veggies together.

Step 5

Add diced onion, cilantro leaves, salt and red pepper flakes to food processor and blend until fully combined.

Step 6

Serve while warm or chill if you prefer cold salsa. Flavor is great served both ways!

Step 7

I personally love have some while it's warm and fresh and then save the other half to eat chilled!
