Why You'll Love This Recipe

Ingredients

For this jarred pasta, I rely on fresh, seasonal vegetables that retain their crunch and color after a quick blanch. Whole‑grain penne gives a hearty bite and holds the sauce well. The lemon‑herb vinaigrette brings acidity and brightness, while olive oil adds richness. Finishing with grated Parmesan and a sprinkle of fresh basil ties everything together into a cohesive, nutrient‑dense meal.

Pasta & Vegetables

• 12 oz (340 g) whole‑grain penne pasta
• 1 cup (150 g) red bell pepper, diced
• 1 cup (130 g) orange carrot, thinly sliced into ribbons
• 1 cup (115 g) yellow summer squash, quartered
• ½ cup (70 g) green peas, frozen and thawed
• ½ cup (50 g) purple cabbage, thinly shredded

Lemon‑Herb Vinaigrette

• ¼ cup (60 ml) extra‑virgin olive oil
• 2 Tbsp freshly squeezed lemon juice
• 1 tsp Dijon mustard
• 1 clove garlic, minced
• ½ tsp dried oregano
• ¼ tsp sea salt
• Freshly ground black pepper, to taste

Finishing Touches

• ¼ cup (20 g) grated Parmesan cheese
• 2 Tbsp fresh basil leaves, chopped

These ingredients work together to create a harmonious balance of texture, flavor, and nutrition. The pasta provides a satisfying chew, while each vegetable contributes a distinct crunch and natural sweetness. The vinaigrette’s acidity cuts through the richness of the olive oil and Parmesan, keeping the dish light yet flavorful. By layering the components in jars, you preserve the individual colors and textures until the moment you’re ready to eat, ensuring every bite is as vibrant as the first.

Step-by-Step Instructions

Cooking the Pasta

Bring a large pot of salted water to a rolling boil. Add the whole‑grain penne and cook according to package directions, usually 9‑11 minutes, until al dente. Stir occasionally to prevent sticking. Once done, drain and rinse briefly under cold water to stop the cooking process and keep the pasta from becoming gummy.

Blanching the Vegetables

While the pasta cooks, bring a second pot of water to a boil. Add the red bell pepper, carrot ribbons, yellow squash, and purple cabbage in batches, blanching each for 30‑45 seconds until just tender yet still bright. The peas need only 1 minute. Immediately plunge the vegetables into an ice‑water bath to lock in color and crunch.

Preparing the Vinaigrette

1. Combine Wet Ingredients. In a medium bowl whisk together olive oil, lemon juice, Dijon mustard, and minced garlic until the mixture emulsifies and looks glossy.
2. Add Herbs & Seasonings. Stir in dried oregano, sea salt, and a generous grind of black pepper. Taste and adjust acidity or salt as needed; the vinaigrette should be bright but balanced.
3. Cool Slightly. Let the dressing sit for 5 minutes while you finish the vegetables. This brief rest allows the garlic flavor to mellow and the herbs to infuse the oil.

Assembling the Jars

Start with a clean 12‑oz mason jar. Spoon a thin layer of the vinaigrette (about 1 Tbsp) at the bottom—this will coat the pasta later. Add a generous handful of cooked penne, then layer the colorful vegetables in rainbow order: red, orange, yellow, green, and purple. Finish with a drizzle of the remaining vinaigrette, a sprinkle of Parmesan, and a few fresh basil leaves. Seal the jar tightly and refrigerate.

Tips & Tricks

Perfecting the Recipe

Flavor Enhancements

For an extra pop, grate a little lemon zest into the vinaigrette or toss in a pinch of red‑pepper flakes. A drizzle of toasted pine nuts adds crunch, while a splash of balsamic reduction brings a subtle sweetness that deepens the overall flavor profile.

Common Mistakes to Avoid

Avoid over‑cooking the vegetables—they should stay crisp, not limp. Also, don’t use too much dressing; excess liquid can make the pasta soggy. Finally, be sure to let the jars cool before sealing; sealing hot jars creates condensation that dilutes the vinaigrette.

Pro Tips

Variations

Ingredient Swaps

Feel free to replace the vegetables with whatever you have on hand—think cherry tomatoes, asparagus spears, or roasted sweet potatoes. Swap the whole‑grain penne for gluten‑free rotini, chickpea pasta, or even spiralized zucchini for a lower‑carb option. A handful of toasted walnuts or sliced almonds can replace pine nuts for added texture.

Dietary Adjustments

To keep the dish vegan, omit the Parmesan and use nutritional yeast or a vegan cheese alternative. For dairy‑free lovers, the vinaigrette already contains no dairy; just replace the cheese. Gluten‑intolerant diners should choose certified gluten‑free pasta and verify that any packaged seasonings are free of hidden wheat.

Serving Suggestions

Serve the jars alongside a crisp mixed green salad tossed in a light vinaigrette, or pair them with a side of roasted chickpeas for extra protein. For a weekend brunch, top each jar with a poached egg and a drizzle of hot sauce for a satisfying twist.

Storage Info

Leftover Storage

Allow the jars to cool completely before sealing. Store them upright in the refrigerator in airtight containers for up to four days. For longer keep‑alive, transfer the contents to freezer‑safe bags, squeeze out excess air, and freeze for up to three months. Label each bag with the date for easy rotation.

Reheating Instructions

To reheat, remove the lid and place the jar (or its contents) in a 350°F (175°C) oven for 12‑15 minutes, covered with foil to retain moisture. Alternatively, microwave the jar’s contents in a microwave‑safe bowl with a splash of water or broth, stirring halfway through for an even 2‑3 minute warm‑up. Add a quick drizzle of fresh vinaigrette before serving to revive the bright flavors.
