This is hands-down the best way to rescue those vegetables lurking in your crisper drawer.

                           As a trained chef, food waste keeps me up at night...

There's something deeply unsettling about watching perfectly good ingredients go bad when so many people struggle to put food on their tables. This concern has shaped how I cook at home—I've developed a daily ritual of taking inventory of what's in my fridge, mentally cataloging what needs to be used first. It's become second nature to plan meals around what's about to expire rather than what I'm craving. Honestly, I love this challenge more than following a rigid meal plan. It forces me to tap into my creativity, to think like the resourceful cooks who came before us, who never wasted a scrap. Some of my family's favorite meals have come from these "rescue missions"—dishes born from necessity that became treasured recipes. This roasted vegetable pasta is a perfect example: it started as a way to save some sad-looking vegetables and quickly became a staple in my menu rotation.

Weeknight Dinner Hero

Busy weeknights call for recipes that work with your schedule, not against it. This pasta checks every box:

• It's largely hands-off (the oven does most of the work)

• Uses one pan for easy cleanup

• Comes together in under an hour

While the vegetables roast, you can help with homework, prep tomorrow's lunch, or simply relax. The result? A dinner that tastes like you spent hours in the kitchen when you spent most of that time doing other things.

Your Go-To Base Recipe for Endless Creativity

Think of this recipe as your culinary foundation rather than a rigid set of rules. Once you master the basic technique—roast vegetables, blend with pasta water, toss with pasta—you can create completely different meals every time. Swap the herbs for different flavor profiles, add various proteins, or use seasonal vegetables. It's like having a cooking template that prevents dinner boredom and keeps your family guessing what delicious combination you'll create next.

Customizing—Once Mastering the Original Recipe!

This pasta is delicious on its own, but adding proteins, swapping veggies, playing with different cheeses, and testing different herbs can transform this dish to make it “uniquely yours”.

Plant-Based Proteins:

• White beans or cannellini beans

• Chickpeas

• Lentils

• Hemp hearts or roasted pumpkin seeds

Lean Animal Proteins:

• Grilled chicken breast

• Turkey meatballs

• Wild-caught salmon

• Shrimp

• Lean ground turkey

Vegetable Swaps: Try zucchini, eggplant, sweet potatoes, or roasted red peppers from a jar.

Cheese Variations: Experiment with Pecorino Romano, fresh mozzarella, a dollop of ricotta, or goat cheese instead of Parmesan.

Spice It Up: Add more red pepper flakes, fresh jalapeños to the roasting pan, or a pinch of smoked paprika.

Herb Alternatives: Fresh basil and oregano are classics, but try rosemary, sage, or even fresh mint for unique flavor profiles.

Bek's Tips for Success

Vegetable Prep: Cut vegetables uniformly for even cooking. Don't skip the parchment paper—it prevents sticking and makes cleanup effortless.

Roasting Perfection: Don't overcrowd the pan. If you need more space, use two baking sheets. The vegetables should sizzle when they hit the hot pan.

Pasta Water is Key: That starchy, salty pasta water is what transforms this from good to great. It helps the sauce adhere to the pasta and creates the perfect consistency.

Sauce Consistency: The sauce should be pourable but not watery. Remember, it will thicken slightly as it cools, so err on the side of slightly loose.

Fresh Herb Timing: Add half the herbs to the roasting vegetables for deep flavor, and save the rest for fresh brightness at the end.

Storage and Make-Ahead Tips

Refrigerator Storage: Store leftovers in the refrigerator for up to 4 days in an airtight container. The flavors improve overnight as they meld together.

Reheating: Add a splash of water or broth when reheating to restore the sauce's consistency. Reheat gently on the stovetop over medium-low heat, stirring frequently, or microwave in 30-second intervals.

Make-Ahead Strategy: Roast the vegetables up to 2 days in advance. Store them in the refrigerator, then blend them into the sauce and combine with freshly cooked pasta when ready to serve.

Meal Prep Friendly: This recipe doubles easily for meal prep. Portion into individual containers with a little extra pasta water to prevent drying out.

Freezing Instructions

Sauce Only: The roasted vegetable sauce freezes beautifully for up to 3 months. Freeze in portion-sized containers or ice cube trays for easy thawing.

Complete Dish: While you can freeze the entire dish, pasta texture suffers in the freezer. For best results, freeze only the sauce and prepare fresh pasta when ready to serve.

Thawing: Thaw frozen sauce overnight in the refrigerator, then reheat gently on the stovetop, adding pasta water or broth to restore consistency.

Ingredients:

For the Roasted Vegetables:

• 1 large onion, diced (about 2 cups)

• 8 to 10 garlic cloves, roughly chopped

• 2 cups fresh tomatoes, roughly chopped (or use cherry tomatoes, halved)

• 1 large red bell pepper, cut into ½-inch pieces

• 2 large carrots, sliced into ¼-inch rounds

• 3 to 4 tablespoons extra virgin olive oil

• Sea salt and freshly ground black pepper, to taste

• ½ teaspoon red pepper flakes (optional, for heat)

For the Pasta and Assembly:

• 1 pound rigatoni pasta (or penne, shells, or rotini)

• 2 to 3 cups fresh baby spinach (adjust to preference)

• 2 cups pasta cooking water, reserved

• Fresh herbs: 3 to 4 tablespoons mixed parsley, basil, oregano, and thyme, divided

• Extra virgin olive oil, for finishing

• Freshly grated Parmesan cheese, for serving

• Fresh lemon juice, optional for brightness

Instructions:

Step 1: Prepare for Roasting

Preheat your oven to 400°F (200°C). Line a large rimmed baking sheet with parchment paper for easy cleanup.

Step 2: Roast the Vegetables

In a large bowl, toss the diced onion, chopped garlic, tomatoes, bell pepper, and carrots with 3-4 tablespoons olive oil. Season generously with salt, pepper, and red pepper flakes (if using). Add half of your fresh herbs and toss until everything is well-coated.

Spread the vegetables in a single layer on your prepared baking sheet—don't overcrowd, or they'll steam instead of roast. Roast for 30-45 minutes, stirring once halfway through, until the vegetables are golden, caramelized, and tender. The edges should be slightly crispy and the tomatoes should be jammy.

Step 3: Cook the Pasta

While vegetables roast, bring a large pot of well-salted water to a rolling boil (it should taste like mild seawater). Cook the rigatoni according to package directions until al dente—usually 1-2 minutes less than the package suggests, as it will continue cooking when combined with the sauce.

Crucial step: Before draining, reserve 2 full cups of the starchy pasta cooking water. This liquid gold will help create the perfect sauce consistency.

Step 4: Create the Magic Sauce

Transfer the roasted vegetables to a blender or food processor. Add ½ cup of the reserved pasta water and blend until you reach your desired consistency. For a completely smooth sauce, blend for 2-3 minutes. For a chunkier texture with some vegetable pieces, pulse just until roughly combined. Add more pasta water gradually if the sauce seems too thick—it should coat a spoon but still flow easily.

Step 5: Bring It All Together

In the same pot you used for pasta (or a large serving bowl), combine the hot, drained pasta with the roasted vegetable sauce. Add the fresh spinach and toss everything together, adding reserved pasta water a little at a time until you achieve a glossy, cohesive sauce that coats every piece of pasta. The spinach will wilt from the heat.

Step 6: Finish with Flair

Drizzle with a generous amount of extra virgin olive oil, sprinkle with freshly grated Parmesan, and garnish with the remaining fresh herbs. Taste and adjust seasoning with salt, pepper, and a squeeze of fresh lemon juice if desired. Serve immediately while hot.

Final Thoughts

This recipe proves that simple techniques can create extraordinary results. The combination of roasted vegetables, starchy pasta water, and fresh herbs creates a dish that's both comforting and sophisticated, perfect for busy weeknights or casual entertaining.
