- 4 cloves garlic, thinly sliced: Infuses the oil and vegetables with a rich, aromatic base.
- 2 c. cherry tomatoes: Burst during roasting, creating a juicy, saucy component.
- 1/4 c. extra-virgin olive oil, plus more for drizzling: The fat that carries flavor and helps vegetables caramelize.

Choosing Your Vegetables

This recipe is wonderfully adaptable feel free to add bell peppers, eggplant, or even fresh corn kernels. The ragĂș will welcome them. This flexibility makes it an excellent companion to other easy, make-ahead dishes like zesty appetizers for a larger summer spread.

Step-by-Step Instructions for a Foolproof RagĂș
Follow these simple steps to create your delicious one-pan dinner. The process is straightforward, but a few key techniques ensure perfection.
Step 1: Preheat and Prep
Begin by preheating your oven to 425°F (220°C). Proper preheating is crucial for getting that immediate sizzle and caramelization when the vegetables hit the pan. While the oven heats, prepare your vegetables. Uniform cutting is important here aim for 1/4-inch thick rounds for the squash and zucchini so they cook evenly. Thinly slice the onion and garlic.
Step 2: Combine and Season
In a 13′ x 9′ baking dish, combine the yellow squash, zucchini, onion, garlic, cherry tomatoes, 1/4 cup of olive oil, and the Aleppo pepper. Season generously with kosher salt and freshly ground black pepper. Use your hands or a large spoon to toss everything thoroughly, ensuring every piece is glistening with oil and seasoned. This step is where you build the foundation of flavor.
Step 3: Roast to Perfection
Place the baking dish in the preheated oven. Roast the vegetables for about 45 minutes, stirring them gently halfway through. This stir ensures even browning and prevents any pieces from burning. You’re looking for the vegetables to become beautifully soft, with deep golden-brown spots and the tomatoes to have collapsed and released their juices.
Step 4: Finish with Herbs and Cheese
Once the vegetables are out of the oven, immediately stir in half of the chopped basil and half of the chopped parsley. The residual heat will wilt the herbs perfectly, releasing their fragrant oils.
Taste and adjust the seasoning with more salt and pepper if needed. Now, scatter the fresh mozzarella pearls over the top, followed by the remaining fresh herbs. Give the whole dish a final, light drizzle of extra-virgin olive oil for a glossy finish and added richness.
Serving Suggestions and Variations
This Summer Vegetable RagĂș is incredibly versatile. Serve it directly from the pan for a rustic, family-style presentation. It’s delicious on its own, but it also pairs wonderfully with crusty bread for soaking up the juices, over a bed of polenta, or tossed with cooked pasta like farfalle or rigatoni.
For a heartier meal, add a can of drained white beans or chickpeas before roasting. This dish is a fantastic, colorful addition to a buffet table alongside other crowd-pleasers like creamy cheese-based sides.
Make-Ahead and Storage Tips
You can chop the vegetables ahead of time and store them in an airtight container in the refrigerator for up to a day. The fully cooked ragĂș stores beautifully. Let it cool completely, then transfer to an airtight container. It will keep in the refrigerator for up to 4 days. Reheat gently in the oven or microwave. Note that the fresh herbs will lose their vibrancy, so you may want to add a fresh sprinkle when serving leftovers.
