Ingredients

Use the exact ingredient amounts below — they’re the basis for the step-by-step directions that follow.

• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 1 small onion, finely chopped (about 1/2 cup)
• 3 cloves garlic, minced
• 1/4 teaspoon red pepper flakes, optional
• 1 pound refrigerated cheese tortellini
• 2 cups low-sodium vegetable broth
• 2 cups fresh baby spinach
• 1/4 cup grated Parmesan cheese, plus more for serving
• Salt and black pepper, to taste
• 1 tablespoon lemon juice, optional

Notes on ingredients

Refrigerated cheese tortellini keeps the cooking time short and guarantees soft, cheesy centers. Use unsalted butter so you control the seasoning amount; if you can’t find low-sodium vegetable broth, dilute regular broth with a little water until the salt level feels right. Fresh spinach wilts quickly, which is why 2 cups is perfect for coating the pasta without overwhelming the skillet. Finish with grated Parmesan and a squeeze of lemon if desired — the acid brightens the dish beautifully.

Equipment

• Large skillet or shallow sauté pan with a lid
• Wooden spoon or silicone spatula
• Chef’s knife and cutting board
• Measuring spoons and cups

Instructions

The directions below are rewritten into clear, step-by-step wording that matches the ingredient amounts verbatim. Follow the steps in order for the best results.

1. Prepare your ingredients. Finely chop the onion, mince the garlic, measure the butter and olive oil, and have the tortellini and broth within reach. Grate 1/4 cup Parmesan and rinse the spinach if needed, but leave it wet; a little moisture helps it wilt quickly into the dish.
2. Heat the skillet over medium heat. Add 2 tablespoons unsalted butter and 1 tablespoon olive oil to the pan. Let the butter melt completely, swirling the pan gently so the oil and butter combine.
3. Brown the butter. Continue to cook, swirling the pan and stirring occasionally, until the butter foams and then turns a deep golden-brown with a nutty aroma — this should take about 2 to 3 minutes. Watch closely so it does not burn. Once browned, immediately lower the heat to medium-low to prevent further darkening.
4. Sauté the onion. Add the finely chopped onion (about 1/2 cup) to the pan and cook in the brown butter for 3 to 4 minutes, stirring frequently, until the onion softens and becomes translucent. Adjust the heat if the onions begin to brown too quickly.
5. Add garlic and red pepper flakes. Stir in 3 cloves minced garlic and 1/4 teaspoon red pepper flakes (if using). Cook for 30 to 45 seconds, just until the garlic becomes fragrant. Do not let the garlic brown.
6. Add tortellini and broth. Pour in 1 pound refrigerated cheese tortellini and 2 cups low-sodium vegetable broth. Gently stir to combine, ensuring the tortellini are submerged in the liquid as much as possible. Increase the heat to medium-high so the broth comes to a gentle simmer.
7. Simmer until cooked. Once simmering, cover the skillet with a lid and let the tortellini cook for 3 to 4 minutes. After that initial time, remove the lid and stir gently, checking the tortellini for tenderness. Continue to cook uncovered for another 2 to 3 minutes if needed, until the tortellini are tender and most of the liquid has been absorbed. The total cooking time for the tortellini should be about 5 to 7 minutes depending on the brand; follow the feel of the pasta rather than a strict timer.
8. Add the spinach. Reduce heat to low. Add 2 cups fresh baby spinach to the skillet in batches if needed. Stir the spinach into the hot tortellini; it will wilt quickly. Continue stirring until all the spinach is incorporated and wilted, about 1 to 2 minutes.
9. Finish with Parmesan, lemon, and seasoning. Sprinkle in 1/4 cup grated Parmesan cheese and 1 tablespoon lemon juice (if using). Stir to melt the cheese and distribute the flavors evenly. Taste and season with salt and black pepper as needed. If the mixture feels dry, add a splash more broth or a drizzle of olive oil to loosen it.
10. Serve. Divide the tortellini among plates or bowls and garnish with additional grated Parmesan. Serve immediately while warm.

Quick tips for success

• Pay close attention during the brown butter step. Butter can go from nutty perfection to burnt quickly, so remove from heat slightly earlier if it looks too dark.
• Do not overcook the tortellini. They should be tender and slightly springy. Check a piece before draining or removing the lid.
• If you like a creamier result, stir in 2 tablespoons of plain Greek-style yogurt or a splash of cream at the end, but that’s optional.
• Want extra protein? Stir in shredded cooked chicken or canned white beans during the last minute of cooking. The one-pot method keeps everything cohesive and saucy.

Make-ahead and storage

This EASY Brown Butter Spinach Tortellini One Pot! is best eaten fresh, but leftovers keep well. Transfer cooled leftovers to an airtight container and refrigerate for up to 3 days. Reheat gently on the stovetop over low heat with a splash of broth or water to loosen the sauce, stirring until warmed through.

Variations and add-ins

• Roasted vegetables: Fold in roasted cherry tomatoes, bell peppers, or zucchini for extra texture and color.
• Herby note: Stir in chopped fresh basil, parsley, or a sprinkle of chopped chives at the end for a bright finish.
• Nutty crunch: Toasted pine nuts or sliced almonds make a lovely contrast when sprinkled over the plated dish.
• Spicy kick: Increase the red pepper flakes to taste for more heat, or drizzle with a little chili oil at the finish.

Serving suggestions

Pair this skillet tortellini with a crisp green salad and crusty bread to mop up that buttery sauce. A simple cucumber-tomato salad with lemon and olive oil keeps the meal light and fresh. For a cozy dinner, serve with roasted vegetables and a glass of your favorite chilled beverage.

Why this works

This recipe leans on three straightforward techniques that together create big flavor: browning butter for depth and nuttiness, sautéing aromatics to build the base, and cooking the tortellini in broth so the pasta absorbs flavor while creating a silky finish. The spinach provides a quick, fresh counterpoint, making the entire dish balanced and satisfying without a long ingredient list or complicated steps.
