How to Make Sweet & Spicy Pickled Peppers, Garlic & Onions

This easy refrigerator-pickle method requires only a few minutes of cooking.

Step 1: Prepare the Vegetables

Wash the mini sweet peppers, jalapeños, and red onion thoroughly.

Thinly slice the sweet peppers and jalapeños into even pieces.

Peel and thinly slice the red onion.

Make sure your garlic cloves are peeled and discard any cloves that are damaged or soft.

Step 2: Pack the Jar

Place the sliced sweet peppers, jalapeños, red onion, and whole peeled garlic cloves into a clean quart-size glass jar.

Alternate the ingredients as you fill the jar so the peppers, onions, and garlic are distributed throughout.

Leave approximately 1 inch of space at the top.

Step 3: Prepare the Pickling Brine

In a medium saucepan, combine:

• White vinegar
• Water
• Granulated sugar
• Kosher salt
• Black peppercorns
• Mustard seeds
• Red pepper flakes
• Dried oregano
• Bay leaves
• Optional coriander seeds

Stir everything together.

Step 4: Heat the Brine

Place the saucepan over medium heat and bring the mixture to a gentle simmer.

Stir until the sugar and salt have completely dissolved.

There’s no need to vigorously boil the brine.

Step 5: Pour the Brine Over the Vegetables

Carefully pour the hot pickling brine into the jar.

Continue pouring until the peppers, onion, and garlic are completely covered.

Make sure the vegetables remain submerged in the liquid.

Step 6: Cool the Jar

Leave the jar uncovered at room temperature for approximately 30–45 minutes, or until cooled.

Step 7: Refrigerate

Once cooled, seal the jar tightly with a lid.

Transfer it to the refrigerator.

Step 8: Allow the Vegetables to Pickle

Refrigerate for at least 24 hours before serving.

This gives the vegetables time to absorb the sweet, spicy, tangy brine.

For a deeper and more developed flavor, allow them to pickle for 3–5 days.

Tips for the Best Pickled Peppers, Garlic & Onions

Slice the vegetables evenly. Similar-sized slices pickle more consistently.

Use firm, fresh vegetables. Fresh peppers, onions, and garlic provide the best crunch.

Use a clean glass jar. Start with a thoroughly cleaned jar and lid.

Wear gloves when handling jalapeños if needed. The chile oils can irritate your skin and eyes.

Don’t touch your face after slicing peppers. Wash your hands, knife, and cutting board thoroughly.

Dissolve the sugar and salt completely. Stir the brine as it heats until no visible granules remain.

Keep everything submerged. The vegetables should remain covered by the vinegar brine during storage.

Wait at least 24 hours. The vegetables need time to absorb the brine.

Give them 3–5 days for deeper flavor. The garlic, spices, peppers, and onions become more integrated as they rest.
