Quick pickles live in the fridge — no canning, no special equipment, ready in 30 minutes and useful for weeks. A jar of pickled red onions or cucumbers turns a plain sandwich, taco, grain bowl, or plate of grilled meat into something noticeably better.
Ingredients
Base brine (covers most vegetables)
- 1/2 cup white wine vinegar or apple cider vinegar
- 1/2 cup water
- 1 tsp fine sea salt
- 1 tsp granulated sugar
Red onions
- 1 medium red onion, halved and thinly sliced (about 2 cups)
Cucumbers
- 2 Persian cucumbers (or 1/2 English cucumber), sliced into 1/4-inch coins
- 1 tsp dill seeds or 2 sprigs fresh dill (optional)
- 1 garlic clove, sliced (optional)
Jalapeños
- 4–5 jalapeños, sliced into 1/4-inch rings (seeds in for more heat, removed for less)
Radishes
- 1 bunch radishes (about 8), thinly sliced or quartered
Method
Make the brine
Combine vinegar, water, salt, and sugar in a small saucepan. Heat over medium, stirring, just until the salt and sugar dissolve — 2 to 3 minutes. You don't need to boil it. Remove from heat.
Pouring hot brine over the vegetables speeds up penetration and softens them slightly; that's ideal for onions and radishes. For cucumbers and jalapeños, you can pour the brine warm or fully cooled — warm gives a softer texture, cooled keeps more crunch.
Prepare the vegetables
- Red onions: Slice thinly, about 1/8 inch. Thin slices pickle faster and are more pleasant to eat.
- Cucumbers: Cut to your preference — coins for topping, spears for snacking alongside food.
- Jalapeños: Rings work for topping. Wear gloves or wash hands immediately after handling; the capsaicin stays on your skin.
- Radishes: Thin slices turn a vivid pink within an hour. Quarters take longer but stay crunchier.
Pack and pour
Pack the vegetables into a clean glass jar (a 16 oz mason jar works well for a single batch). Add any aromatics — dill, garlic, peppercorns — now. Pour the brine over the top, pressing the vegetables down so they're submerged. Seal and let cool to room temperature, then refrigerate.
Timing before eating:
- Red onions: 30 minutes minimum, best after 2 hours
- Cucumbers: 1 hour minimum, best after 4 hours
- Jalapeños: 1 hour, fully pickled by 24 hours
- Radishes: 30 minutes for color, 2 hours for full flavor penetration
Storage
- Container: Glass jar with a tight lid — avoid reactive metals
- Fridge: 2–3 weeks; quality peaks in the first week
- Freezer: Not recommended — freezing destroys the crunch
Notes
- Quick pickles vs. canning: These are refrigerator pickles only. Shelf-stable canning requires a specific process — sterilized jars, proper acid ratios, and a water bath — to be food-safe. These are not shelf-stable; keep them in the fridge and treat them like any perishable.
- Brine ratios: 1:1 vinegar to water is the neutral baseline. Go heavier on vinegar (up to 3:1) for a sharper pickle. Add more sugar (up to 1 tbsp) for a bread-and-butter style sweetness. More salt draws moisture from the vegetable and intensifies flavor.
- Vinegar choices: White wine vinegar is clean and neutral — use for onions and radishes where you want the vegetable color to show. Apple cider vinegar adds a mild fruity depth, good with cucumbers and jalapeños. Rice vinegar is gentler and slightly sweet, excellent for cucumbers if you want a Japanese-adjacent flavor. Plain white distilled vinegar works but tastes harsh; add a little more sugar to balance it.
- The brine turns bright pink with red onions and magenta with radishes — this is expected and makes the jar look excellent
- Reuse the brine once for a second batch — it won't be as strong, but it works
Variations
- Bread-and-butter cucumbers: Double the sugar (2 tsp), add 1/4 tsp turmeric and 1/4 tsp mustard seeds to the brine for a classic sweet pickle flavor.
- Pickled ginger: Slice fresh ginger very thin (a vegetable peeler works). Use unseasoned rice vinegar, 2 tsp sugar, and 1/2 tsp salt. The ginger turns pink on its own if you're using young ginger. Ready in 24 hours.
- Spiced red onions: Add 1/2 tsp whole cumin seeds, 4 black peppercorns, and a pinch of dried oregano to the jar. Common in Mexican and Latin cooking.
- Pickled cabbage: Shred 2 cups red or green cabbage, pack tightly into the jar. The firmer texture can handle the brine being poured hot; it's ready in 2 hours and holds well for 3 weeks.
