Quick Pickled Red Onions & Radishes (For Two 8oz Jars)




There’s something magical about a jar of quick pickles in the fridge — they add that bright, tangy pop to everything from tacos to grain bowls. This easy, small-batch recipe is perfect for when you want a fresh, flavorful condiment without having to break out the canning gear.
Why Red Onions & Radishes?
Both are naturally crisp, colorful, and just a little spicy, making them the perfect candidates for a quick pickle. Red onions mellow and turn a beautiful blush pink, while radishes keep their crunch and develop a sharp-sweet edge. It’s flavor meets freshness in every bite.
🌿 What You’ll Need (For Two 8 oz Jars)
Brine:
- 1cup water
- 1 cup vinegar (white & apple cider)
- 2 tablespoons sugar
- 1 teaspoon kosher salt
Vegetables:
- 1 medium red onion, thinly sliced
- 8 radishes, thinly sliced
Today I used French or sometimes called Breakfast radishes.
Optional Add-ins (customize to your taste):
- Black peppercorns
- Mustard seeds
- Garlic (2 gloves in each jar)
- Fresh herbs (thyme)
🔪 How to Make Them
- Prep the veggies. Slice your onion and radishes thin (a mandoline makes it easy). Pack them into clean 8 oz jars.
- Make the brine. In a small saucepan, combine water, vinegar, sugar, and salt. Heat until just simmering and everything is dissolved.
- Add flavor. Drop a few spices or herbs into each jar, if using.
- Pour & pickle. Pour warm brine over the veggies until fully covered.
- Cool & chill. Let them cool to room temperature, then seal and refrigerate.
🕒 Ready When You Are
- Red onions: ready in 30–60 minutes
- Radishes: best after a few hours or overnight
These will stay bright and crisp in the fridge for up to 2–3 weeks — though they rarely last that long. Write the days on the jar.
🥗 Healthy, Bright & Versatile
These pickles are low-calorie, naturally gluten-free, and made with minimal sugar. Plus, vinegar helps bring out digestive benefits and keeps things fresh without preservatives.
💡 How to Use Them

🍯 Honey Quick Pickle Brine (for Cucumbers)
Base Recipe (for ~2 cups brine):
- 1 cup vinegar (white, apple cider, or rice vinegar)
- 1 cup water
- 2 tablespoons honey (adjust to taste)
- 1 tablespoon kosher salt
Optional Add-ins:
- Crushed garlic cloves
- Dill sprigs or seeds
- Mustard seeds
- Red pepper flakes
- Sliced onion
🥒 Tips:
- Dissolve the honey: Warm the brine slightly to help the honey dissolve fully, but don’t boil it if you want to preserve its delicate flavor.
- Flavor profile: Honey gives a slightly floral, rich note. It’s less sharp than white sugar and works great in more nuanced or herby pickle blends (like cucumber + dill + garlic).
- Storage: Keep refrigerated. These pickles are best eaten within 2–3 weeks.
