Slow Roasted Tomato Farro Salad

The first time I slow-roasted tomatoes, my entire apartment smelled like an Italian grandmother's kitchen in mid-August. I had no idea that shrinking cherry tomatoes in a low oven could transform them into candy-sweet jewels that would completely change how I thought about grain salads. This farro combination has been my go-to summer dish ever since, perfect for those nights when cooking feels like too much but you still want something that feels special.

I brought this salad to a friend's rooftop dinner party last summer, and people literally hovered around the bowl. The contrast between the sweet shriveled tomatoes, peppery arugula, and tangy balsamic dressing creates this perfect bite that nobody can quite put their finger on. My friend Sarah still texts me every few months asking for the recipe because her husband keeps requesting it.

Ingredients

• Cherry or grape tomatoes: 500 g, halved. The smaller ones concentrate more sweetness during slow-roasting, and grape tomatoes tend to hold their shape better than larger cherry varieties.
• Extra virgin olive oil: 2 tbsp for roasting plus 3 tbsp for dressing. Use something fruity and robust since the oil flavor really shines through in both the tomatoes and the final salad.
• Sea salt and black pepper: 1 tsp salt and ½ tsp pepper for the tomatoes. The slow-roasting intensifies the saltiness, so dont be afraid to season generously before they hit the oven.
• Dried oregano: 1 tsp. Rub it between your fingers before sprinkling to wake up the oils and get that classic Mediterranean aroma going.
• Farro: 200 g (about 1 cup), rinsed. Look for semi-pearled farro which cooks faster while still maintaining that satisfying chew. Whole farro works too but needs overnight soaking and longer cooking time.
• Water or vegetable broth: 1 L (4 cups). Broth adds a subtle depth of flavor that water doesnt, but either works perfectly fine.
• Red onion: 1 small, thinly sliced. Soak the sliced onion in ice water for 10 minutes if you want to mellow out the sharp bite.
• Baby arugula or spinach: 75 g. Arugula adds a nice peppery kick that cuts through the sweetness of the roasted tomatoes.
• Fresh herbs: 10 basil leaves torn and 2 tbsp parsley chopped. Tear the basil by hand instead of cutting it to prevent bruising and those dark edges that make it look sad.
• Balsamic vinegar: 1½ tbsp. The acidity cuts through the rich farro and sweet tomatoes, balancing everything perfectly.
• Garlic clove: 1 small, minced. Let it sit in the dressing for at least 10 minutes to mellow out and infuse the vinegar.
• Dijon mustard: 1 tsp. This is the secret that emulsifies your dressing and makes it cling to every grain of farro.
• Honey or maple syrup: ½ tsp. Just a tiny amount helps round out the acidity and brings all the flavors together.
• Feta cheese: 60 g crumbled. The salty creamy tang is optional but highly recommended, even if you just use a light sprinkling.
• Toasted pine nuts or walnuts: A handful adds lovely crunch and nutty flavor that complements the farro beautifully.

Instructions

Get those tomatoes roasting:

Preheat your oven to 130°C (265°F) and line a baking sheet with parchment paper. Halve your cherry tomatoes and arrange them cut side up like little boats. Drizzle with olive oil and sprinkle with sea salt, pepper, and oregano, then use your hands to gently toss everything together until each tomato is glistening.

Let the oven work its magic:

Slide the tomatoes into the low oven and forget about them for 1½ hours. They'll shrink down and wrinkle up, concentrating all that natural sugars into something incredibly sweet and intense. Your kitchen will start smelling amazing.

Cook the farro while you wait:

Bring your water or broth to a boil in a medium pot, add a teaspoon of salt, then dump in the rinsed farro. Turn the heat down to a gentle simmer and cook for 25 to 30 minutes until the grains are tender but still have a nice chewy bite. Drain any excess liquid and let it cool slightly so it doesnt wilt the greens.

Whisk up the dressing:

In your large mixing bowl, combine the olive oil, balsamic vinegar, minced garlic, Dijon mustard, honey, and some salt and pepper. Whisk vigorously until it thickens slightly and emulsifies into a glossy dressing.

Bring it all together:

Add the cooked farro, those beautiful roasted tomatoes, sliced red onion, greens, basil, and parsley to the bowl with the dressing. Use two spoons or gentle hands to toss everything together until each grain is coated and the ingredients are evenly distributed.

Taste and adjust:

Take a bite and add more salt, pepper, or dressing if needed. Sometimes the farro soaks up more than you expect. Transfer to a pretty serving platter and scatter with crumbled feta and toasted nuts if you're using them.

Save

This recipe became my entire contribution to family gatherings one summer. My mom started requesting it specifically, saying it reminded her of the grain salads she ate in Tuscany, except better because the slow-roasted tomatoes added this depth you just cant get from fresh ones. There's something deeply satisfying about serving a dish that looks impressive but comes together so effortlessly.

Make It Your Own

I've tried swapping pearl barley and wheat berries for the farro, and while they both work beautifully, farro still wins for that perfect chewy-tender balance. Sometimes I'll add grilled chicken or a can of drained chickpeas if I want it to be more of a complete meal, especially for lunch the next day.

Serving Suggestions

This salad pairs beautifully with grilled fish or roasted chicken, but honestly it's substantial enough to stand alone as a light dinner. A crisp Sauvignon Blanc cuts through the richness perfectly, though any dry white wine would work just as well.

Storage and Meal Prep

The salad keeps beautifully in the refrigerator for 3 to 4 days, though I recommend adding the fresh herbs and arugula right before serving so they don't get sad and wilted. The flavors actually develop and meld together overnight, making it one of those rare dishes that tastes even better as leftovers.

• Store the toasted nuts separately and add them right before serving to maintain their crunch
• If meal prepping, keep the dressing on the side and toss everything together just before eating
• Bring the salad to room temperature for about 20 minutes before serving to let the flavors really shine

There's something about this salad that feels like a hug in a bowl. It's the kind of dish that makes you slow down and actually enjoy your lunch, even on a busy Tuesday.

Recipe FAQs

→ Can I make this ahead of time?

Yes, this dish actually improves after a few hours in the refrigerator. The flavors meld together beautifully. Store in an airtight container for up to 4 days, bringing to room temperature before serving.

→ What can I substitute for farro?

Pearl barley, wheat berries, or spelt work well as alternatives. Keep in mind cooking times may vary slightly—barley takes about 45 minutes, while wheat berries need 50-60 minutes to become tender.

→ Is slow-roasting tomatoes necessary?

Slow-roasting at low temperature is key—caramelizes the tomatoes and concentrates their natural sugars. Quick roasting at high heat won't achieve the same depth of flavor or chewy, candy-like texture.

→ Can I use regular tomatoes instead of cherry tomatoes?

Cherry or grape tomatoes are ideal because their size allows them to roast evenly without becoming watery. Larger tomatoes can work if diced, but you may need to adjust roasting time to prevent excess moisture.

→ How do I store leftovers?

Keep refrigerated in an airtight container for up to 4 days. The farro will absorb some dressing, so you might want to refresh with a splash of olive oil and vinegar before serving leftovers.

→ Can I add protein to make it a complete meal?

Absolutely. Grilled chicken, chickpeas, white beans, or even shredded salmon work beautifully. The Mediterranean flavors pair well with most proteins, making it incredibly versatile.
