1 medium (170 g) red bell pepper, seeded and cut into ½-inch (1.25 cm) pieces

Equipment (7)

Large non-reactive bowl (glass, ceramic or stainless), at least 4-quart (4 L)

Small non-reactive saucepan (2-quart / 2 L)
Sharp chef's knife and cutting board
Measuring cups and spoons
Clean kitchen towels or paper towels

Steps

Before you start

Plan ahead: the vegetables brine for 12 hours, then marinate in the fridge at least 2 days (48 hours) before eating. Best after 5 days.
Wash two 1-quart (1 L) jars and lids in hot soapy water and rinse well. This is a refrigerator pickle, so full canning sterilization is not needed.
Use non-iodized salt (kosher or pickling salt). Iodized salt can cloud the brine and dull the flavor.
Cut all vegetables to a similar bite-size so they brine and marinate evenly.

1
Cut the vegetables
- Trim the cauliflower into ¾-inch (2 cm) florets, cutting large ones through the stem so all pieces are similar.
- Slice the celery ¼ inch (6 mm) thick on the diagonal, peel and slice the carrots ¼ inch (6 mm) thick, and cut the red bell pepper into ½-inch (1.25 cm) pieces.
- Place everything in a large non-reactive bowl.

Ready when: Pieces are uniform in size, with no florets larger than about 1 inch (2.5 cm).
Tip: Uniform pieces brine and pickle evenly, so no bite is raw-tasting or mushy.
2
Make the salt brine
- In a large measuring cup or bowl, stir the kosher salt into the cold water for 1–2 minutes until no grains remain on the bottom.
- Pour over the vegetables.
- Add more cold water if needed so everything is submerged, and set a plate on top to keep the vegetables down.
+ Show details− Hide details
Ready when: Water is clear with no visible salt crystals, and vegetables are fully submerged.
Tip: If using table salt, reduce to 3 tablespoons (45 g) since it is denser than Diamond Crystal kosher salt.
3
Brine overnight
- Cover the bowl and leave it at cool room temperature (under 70°F / 21°C) for 12 hours, or overnight.
- If your kitchen is warm, refrigerate it for the same time.

Ready when: Vegetables look slightly glossy and taste lightly salty; a cauliflower floret bends slightly but still snaps.
4
Drain and rinse
- Drain the vegetables in a colander and rinse thoroughly under cold running water for about 1 minute, tossing so every piece is rinsed.
- Shake well, then spread on clean towels and pat dry for 5 minutes.

Ready when: Vegetables taste only mildly salty and look dry on the surface, not dripping.
Tip: Skipping the rinse will make the finished giardiniera too salty.
5
Heat the marinade
- In a small non-reactive saucepan, combine the white wine vinegar, ½ cup (120 ml) water, sugar, garlic, chili flakes, oregano, peppercorns and bay leaves.
- Bring to a gentle simmer over medium heat, stirring to dissolve the sugar, about 4 minutes.
- Simmer 1 minute more, then remove from the heat.

Ready when: Sugar is fully dissolved and the liquid is steaming with small bubbles at the edges.
Tip: Open a window; hot vinegar and chili fumes are sharp.
6
Cool the marinade
- Let the marinade cool for 15 minutes until warm, not hot (about 110°F / 43°C).
- Stir in the olive oil.

Ready when: The pan is comfortable to touch on the side and the liquid is warm, not steaming.
Tip: Pouring boiling-hot liquid onto the vegetables will soften them and cost you crunch.
7
Pack the jars
- Divide the dried vegetables between two clean 1-quart (1 L) jars, packing them in snugly and leaving about 1 inch (2.5 cm) of headspace.
- Pour the marinade, including the garlic, chili and spices, evenly over both jars, tucking a bay leaf in each.
- Press the vegetables down with a spoon to release air bubbles.
+ Show details− Hide details
Ready when: Liquid reaches within ½ inch (1.25 cm) of the top and covers most of the vegetables.
Tip: Vegetables poking above the liquid should be pushed down daily; a little exposure is fine, since the oil layer protects them.
8
Marinate in the fridge
- Seal the jars and let them stand on the counter for 1 hour, then refrigerate.
- Turn the jars upside down once a day to redistribute the oil and spices.
- Marinate for at least 48 hours; the flavor is best after 5 days.

Ready when: Cauliflower is tangy through to the center, still crisp, and the brine is orange-tinted from the chili.
Tip: The olive oil will turn cloudy and solidify when cold; it loosens within 10 minutes at room temperature.

Good to know

Tips

Keep the vegetables crisp by cooling the marinade before pouring and never boiling the vegetables in it.
Use only non-reactive bowls and pans (glass, ceramic, stainless); aluminum or cast iron will react with the vinegar and give a metallic taste.
For a milder giardiniera, cut the chili flakes to 2 teaspoons; for more heat, add 1 more tablespoon.
Always use clean utensils to take pickles from the jar to extend fridge life.

Make ahead

"Best made 3–5 days before serving. The vegetables brine for 12 hours, then marinate at least 2 days in the fridge, and the flavor keeps improving for about a week."

Storage & reheating

"Refrigerator: keep covered in the marinade for up to 4 weeks, always using a clean fork or spoon. Room temperature: serve for up to 2 hours; return to the fridge after. Freezer: not recommended, as the vegetables turn soft. Serve cold or let sit 10 minutes to loosen the olive oil."

Substitutions

white wine vinegar (5–6% acidity) → red wine vinegar or apple cider vinegar (5% acidity). Red wine vinegar gives a deeper color and bolder flavor; cider vinegar is slightly fruitier. Keep the same amount.
red chili flakes → 2 thinly sliced fresh serrano or Fresno chiles. Gives a fresher, brighter heat; use 1 tablespoon (6 g) flakes for a milder version.
red bell pepper → pepperoncini or sport peppers, sliced. Classic Chicago-style addition; use the same weight and reduce the chili flakes if you want less heat.
extra-virgin olive oil → neutral oil such as canola. Won't solidify as much in the fridge, though it has less flavor.
