This radicchio salad recipe makes a big, beautiful salad that’s perfect to serve family-style on a big platter when company comes — or anytime you’re craving something more interesting to eat than a basic green salad. You’ll learn the best way to cut, prepare, and eat radicchio with this easy recipe.
What sets this salad apart is the combination of ingredients that touches every one of your taste buds. We’re talking sweet, salty, bitter and sour, not to mention plenty of savory crunch!
Key ingredients
- Radicchio: Like most chicories, radicchio has a bitter taste profile. The most familiar type found in grocery stores is (and the one used in this recipe) is the round Chioggia variety. Other radicchio types include Treviso, Tardivo, and Castelfranco, which can sometimes be found at farmer’s markets or in specialty grocery stores. I’ve made this salad many times, and found that one medium or 2 small heads (3/4 pound) of radicchio yields about 6 cups sliced radicchio, which is the sweet spot.
- Arugula: This nutty-tasting salad green adds color and tempers some of the bitterness of the radicchio. I love to pair arugula salads with nuts and soft cheeses because you can always count on them to be a winning combo.
- Red onion: The sweet sharpness of red onion is really tasty with bitter greens, and on any salad. You can substitute with 1/2 cup chopped green onion.
- Walnuts: This nut is a perfect partner for any type of bitter green. I use them as a crunchy garnish for the salad, toasted and lightly seasoned with rosemary and sugar. If you’re short on time, you can simply use plain roasted, salted walnuts, or use store-bought glazed walnuts or almonds.
- Blue cheese: Tangy, creamy blue cheese has a distinctive taste and texture that can stand up to bold flavors in the salad. Swap it out with another soft, salty cheese such as feta or goat cheese.
Radicchio is not a timid vegetable — it needs a salad dressing that can match it’s bold character. A classic balsamic vinaigrette doubles-down on the bittersweet ingredients for a pleasant flavor contrast.
Make the salad
1. Quickly rinse the whole radicchio head under cold water. Pat dry with a clean towel. 2. Remove tough or damaged outer leaves, and trim off the stem end.
3. Slice the head in half. 4. Cut out the wedge-shaped core and discard.
5. Slice each half into 1/2-inch lengths. 6. Turn the slices crosswise and chop into bite-size pieces. The prepped and sliced radicchio will keep up to 3 days, refrigerated in a sealed bag.
7. Put the arugula and radicchio in a large bowl. 8. Add the sliced onion and half of the blue cheese.
10. Add 2-3 tablespoons of the dressing. 11. Toss the salad gently to avoid bruising the tender leaves. 12. Sprinkle with the toasted walnuts and remaining cheese.

Karen’s Notes and Tips
- This recipe makes a big salad, enough for 6-8 servings.
- The prepped and sliced radicchio (without dressing) will keep up to 3 days, refrigerated in a sealed bag.
- Make ahead: Assemble the salad without the dressing up to one day ahead and refrigerate. Toss with the vinaigrette just before serving.
- Instead of making the Rosemary Walnuts, use plain roasted, salted walnuts, or store-bought glazed walnuts or almonds.
- Tangy, creamy blue cheese has a distinctive taste and texture that can stand up to bold flavors in the salad. Swap it out with another soft, salty cheese such as feta.
- Add cooked bacon or crumbled baked prosciutto crisps for a savory, salty hit.
- Toss in 1/4 cup dried sour cherries, cranberries or diced pear.

This was so good! Instead of the blue cheese, I had cranberry stilton which was great with this! I also diced a shallot into the dressing instead of the red onion, since I had a shallot. I could eat this every night!!
I wish I had cranberry stilton because that sounds PERFECT with the radicchio in this salad! 🤩
