Garlic Tomato Gluten-Free Pasta with Spinach

Last updated: August 30, 2026

Garlic, cherry tomatoes, spinach, herbs, and Parmesan make a simple skillet sauce for gluten-free pasta. Package cooking directions remain important because rice-, corn-, legume-, and quinoa-based pastas soften at different rates.

Yield, timing, and equipment

• Yield: 4 servings.
• Serving definition: one-quarter of the finished pasta, about 1¾ cups depending on pasta shape.
• Prep time: 15 minutes.
• Cook time: 20 minutes.
• Total time: about 35 minutes.
• Equipment: 6-quart pot, colander reserved for gluten-free preparation when needed, 12-inch skillet, chef’s knife, cutting board, measuring cups and spoons, tongs, and ladle.

Ingredients

• 12 ounces (340 g) pasta labeled gluten-free
• Water for boiling, according to the pasta package and pot size
• 1 tablespoon kosher salt for the cooking water, or the package-directed amount
• 2 tablespoons olive oil
• 1 small yellow onion, finely diced
• 3 garlic cloves, minced
• 2 cups cherry tomatoes, halved
• 3 cups loosely packed spinach
• ½ teaspoon dried oregano
• ½ teaspoon dried basil
• ¼ teaspoon black pepper
• ¼ teaspoon red-pepper flakes, optional
• ½ cup (45 g) finely grated Parmesan
• ½ cup reserved pasta cooking water, used as needed
• ¼ cup fresh basil leaves, washed and torn, optional

Cook the pasta and sauce

1. Read every packaged ingredient label. If gluten cross-contact must be controlled, use cleaned cookware, a colander, utensils, and work surfaces that have not contacted gluten-containing pasta or crumbs. Wash the tomatoes, spinach, and basil under running water.
2. Bring the water to a full boil and add salt. Add pasta and set a timer for the earliest package-directed doneness. Stir immediately and several times during cooking. Gluten-free pasta should be tender but still hold its shape.
3. Before draining, reserve ½ cup cooking water in a clean measuring cup. Drain promptly; do not rinse unless the package specifically instructs it.
4. While pasta cooks, heat olive oil in the skillet over medium heat. Cook onion for 4 minutes. Add garlic and stir for 30 seconds.
5. Add tomatoes, oregano, basil, black pepper, and optional red-pepper flakes. Cook for 6 to 8 minutes, stirring, until tomatoes soften and release juice. Add spinach and cook 1 to 2 minutes until wilted.
6. Add drained pasta and ¼ cup reserved water. Toss gently for 1 to 2 minutes. Add more reserved water 1 tablespoon at a time only if needed to coat the pasta.
7. Remove from heat, fold in Parmesan, and divide immediately into four portions. Add fresh basil after it has been washed and torn on a clean surface.

Substitutions

• Choose any pasta shape labeled gluten-free, but follow that package’s time and liquid guidance.
• Use a labeled dairy-free grated topping or omit Parmesan for a milk-free variation; verify all ingredients independently.
• Use arugula in place of spinach and add it after removing the skillet from heat.
• Add 1 cup cooked white beans for a different variation, after checking the package label and rinsing them.

Storage, freezing, thawing, and reheating

Refrigerate within 2 hours in shallow airtight containers and use within 3 to 4 days. Gluten-free pasta often softens after freezing, so freezing is not recommended for best texture; if frozen, use within 1 month and thaw in the refrigerator. Reheat covered with a splash of water until the center reaches 165°F (74°C). Discard pasta held out longer than 2 hours, or longer than 1 hour above 90°F (32°C).
