How to Store Radicchio

Radicchio, with its vivid purple leaves and distinct bitter flavor, is a winter season staple that enhances a variety of dishes.

To keep your radicchio fresh, it’s essential to store it properly.

While this vegetable is hardy, its crispness and flavor can be preserved through specific storage techniques.

When you bring radicchio home, always start by placing it in a cold environment.

Optimal storage temperatures are crucial; maintaining your refrigerator’s temperature between 32°F and 40°F (0°C to 4°C) can significantly slow down the decay process and maintain the texture of the leaves.

To begin, you should clean the radicchio under cold water, shake off excess moisture, and pat it dry.

Once cleaned, wrap the radicchio in paper towels to absorb any remaining water.

This step is key in preventing spoilage caused by excess moisture.

Finally, place the wrapped radicchio into an airtight container or a perforated plastic bag.

This will keep it in a moist condition without being too wet, retaining freshness for an extended period.

Store it in the vegetable crisper section of your refrigerator, away from ethylene-producing fruits to avoid premature spoilage.

Selecting Quality Radicchio

When shopping for radicchio, seek out heads that are firm and possess vibrant color. These characteristics are indicative of the vegetable’s freshness and quality.

Identifying Freshness

Visual Inspection: Your primary tool is observation.

  • Look for compact heads that are free from browning or substantial wilt.
  • A quality radicchio should have a vibrant color—whether it’s the deep red of Chioggia, the varied hues of Treviso, or the more delicate tones of Castelfranco.
  • The leaves should be firm to the touch, indicating freshness.

Leaf Texture: Gently feel the leaves.

  • They should be tight and resilient, not limp or excessively soft.

Choosing Varieties

Chioggia: This variety is rounded with dark red leaves and white ribs. Ensure its leaves are tightly packed and rich in color for the best quality.

Treviso: Treviso has elongated heads resembling Belgian endive. Its leaves should be similarly firm and show a bright red hue with white streaks.

Castelfranco: Variegated with a softer texture, Castelfranco radicchio should still be selected for its firmness and absence of blemishes on its speckled, cream-colored leaves.

Storing Radicchio

When storing radicchio, you want to preserve its freshness, avoid excess moisture, and prevent premature wilting.

By following proper refrigeration techniques and understanding how to extend its shelf life, you can easily maintain the quality of this leafy vegetable.

Refrigeration Techniques

Your refrigerator is the ideal place to store radicchio.

You should store it in the vegetable crisper drawer, which provides a consistent environment for maintaining freshness.

Keep the temperature between 32°F and 40°F (0°C to 4°C) to slow the natural decay process.

  • Step 1: Rinse radicchio under cold water for 15-30 seconds.
  • Step 2: Shake off excess water and pat the leaves dry with a paper towel.
  • Step 3: Place radicchio in a plastic bag; a perforated plastic bag is best to allow some air circulation.
  • Step 4: Put the bag in the crisper drawer of your refrigerator.

Extending Shelf Life

To extend the shelf life of radicchio, proper preparation is key:

  1. Dry the leaves thoroughly: Dampness can lead to faster spoilage.
  2. Wrap in paper towels: This step absorbs any residual moisture.
  3. Use an airtight container or a sealed plastic bag: This helps retain freshness and extend shelf life.

Avoiding Moisture and Wilting

Radicchio can wilt or spoil quickly if exposed to too much moisture.

  • Moisture control: Wrap radicchio in paper towels to absorb moisture.
  • Proper bagging: If using a plastic bag, ensure it’s loosely tied or perforated to allow for some airflow.
  • Regular checks: Inspect your radicchio regularly, and remove any wilted or damaged leaves to prevent the spread of decay.

Preparing Radicchio for Storage

Proper preparation of radicchio is essential for maintaining its freshness. This includes careful cleaning, thorough drying, and adequate wrapping before storage.


You must start by cleaning your radicchio to remove any dirt and debris.

Gently rinse each head under cold running water for approximately 15-30 seconds.

Be mindful to inspect for and remove any wilted leaves during this process.


After rinsing, it is critical to ensure all excess water is removed as moisture can lead to quicker spoilage.

Shake off the water, then pat the radicchio dry using clean paper towels or employ a salad spinner to remove moisture efficiently.


To maintain humidity levels and keep radicchio fresh:

  1. Lay out a clean paper towel.
  2. Wrap the radicchio head loosely in the paper towel to absorb any residual moisture.
  3. Ensure that the leaves are not overly packed as this can cause bruising and hasten decay.

Using Radicchio in Cooking

Raw Preparations

You can enjoy radicchio raw in various salads where its bold bitterness pairs well with sweeter and creamier ingredients.

When using radicchio raw, consider the following:

  • Mix into salads: Enhance a mesclun mix or slaw with torn radicchio leaves for a refreshing bite or toss with a tangy vinaigrette to contrast the bitterness.
  • Use as a base for dishes: Substitute radicchio for traditional greens in your next salad. The firm leaves can withstand robust dressings and additional hearty toppings such as nuts and cheese.

Cooking Techniques

When cooked, radicchio mellows in bitterness and can add depth to a wide array of dishes. Here are some techniques to best utilize radicchio:

  • Grilling: Cut radicchio into wedges and brush lightly with oil before placing on a grill. The char enhances its natural flavors and adds smokiness that complements meats or grilled vegetables.
  • Roasting: Roasting the leaves whole or chopped can concentrate the sweetness. Pair it with olive oil and a sprinkle of salt for a simple side dish.
  • Sautéing: Sliced radicchio can be sautéed until wilted and becomes an excellent addition to pasta or risotto.

Preservation Methods

Proper preservation of radicchio ensures that its crisp texture and bitter flavor are maintained. These methods will help prolong the freshness of radicchio in your kitchen.

Freezing Radicchio

To freeze radicchio, first wash the leaves and pat them dry. You can then chop the radicchio into your desired size.

Blanching the leaves before freezing can help retain color and texture.

To do this, immerse the leaves in boiling water for two minutes, followed by an ice bath.

After blanching, dry the leaves thoroughly to prevent ice crystal formation.

Place the radicchio in an airtight container or freezer bag, removing as much air as possible before sealing.

Label the container with the date, and your radicchio can be stored in the freezer for up to eight months.

Long-Term Storage Solutions

For refrigerated storage, keep radicchio in a cold and moist environment, ideally between 32°-40°F (0°-5°C) with 95 percent relative humidity.

Utilize the vegetable crisper section of your refrigerator for the best results.

Store radicchio in a loosely tied plastic bag with holes to maintain the right humidity level.

It’s important to keep radicchio away from ethylene-producing fruits and vegetables as ethylene can accelerate spoilage.

In these conditions, radicchio can last for three to four weeks.
