Pickled Jalapeño Brine Recipe

In true Hey! I Can Do That fashion, this past spring (2025) I decided I was going to plant a garden… and wow, has it outdone itself! We’ve made spaghetti sauce, pizza sauce, and now—pickled jalapeños!

It’s officially November, but my garden is still thriving. I ended up harvesting about a pound and a half of a mix of jalapeños and “Spicy Jane” peppers (they pack about the same heat level as jalapeños). We already have plenty frozen for fajitas and burgers, so I thought, let’s make some pickled peppers!

Because really, how many peppers can Peter Piper pick before he just pickles them? 😂


🥒 Gather Your Supplies

Here’s what you’ll need to make this easy pickled jalapeño brine:

  • 2 cups white vinegar
  • 2 cups water
  • 2 tablespoons pickling salt
  • 2 teaspoons sugar
  • 1½ pounds jalapeños or mixed hot peppers
  • Garlic Bulb, about 2 each jar peeled and smashed
  • Mustard seed (about ¼ teaspoon per jar)
  • Half-pint or pint jars with lids and bands
  • A large saucepan for making the brine
  • Tongs and a canning rack (for water bath processing)

🔥 Let’s Get Pickling

  1. Prepare the brine:
    In a large saucepan, combine 2 cups white vinegar, 2 cups water, 2 tablespoons pickling salt, and 2 teaspoons sugar.
    Heat on medium until it comes to a gentle boil.
  2. Prep the peppers:
    Slice your jalapeños into rings (you can leave some whole if you prefer). Peel and lightly smash the garlic cloves.
  3. Fill the jars:
    • Place 2 garlic cloves in the bottom of each half-pint jar.
    • Add ¼ teaspoon of mustard seed to each jar.
    • Pack the jars tightly with sliced jalapeños.
  4. Add the brine:
    Ladle the hot brine into each jar, leaving ½ inch of headspace at the top.
    Wipe the rims clean and place your lids on snugly.
  5. Hot water bath:
    Place the jars in a boiling water bath for 15 minutes (based on my research for my area—be sure to check your local guidelines for altitude adjustments).
  6. Cool and store:
    Once processed, let your jars cool completely. You’ll hear that satisfying pop as they seal!

I ended up with three half-pint jars, which I think will make the cutest little gifts for co-workers, teachers, or neighbors.


🍔 How to Use Pickled Jalapeños

These are delicious on just about everything:

  • Burgers and hot dogs
  • Pizza (hello, spicy pepperoni!)
  • Nachos or tacos
  • Sandwiches or wraps
  • Or honestly… straight from the jar for a little snack!

The heat level depends on how spicy your peppers were to begin with, but the flavor is perfectly tangy with just the right kick.


💡 Bonus Tip!

Don’t toss those pepper tops! I saved all the little ends and tips in a bowl—perfect for making my Jalapeño Simple Syrup.
