In a large pot of boiling salted water, cook the beef tortellini according to package instructions until al dente. Drain and set aside.
In a large skillet over medium heat, melt the butter.
Once the butter is melted and bubbly, add the minced garlic and red pepper flakes, sautéing for about 1-2 minutes until fragrant but not browned.
Add the halved cherry tomatoes into the skillet and stir for about 3-4 minutes until they start to soften.
Incorporate the spinach leaves and cook for another minute until wilted.
Toss the drained tortellini into the skillet, mixing gently to coat them in the garlic butter and combine all ingredients. Season with salt and pepper to taste.
Sprinkle the grated Parmesan cheese over the pasta and give it one last gentle stir to combine.
Plate the tortellini and garnish with fresh basil leaves for an aromatic finish.
Notes
Adjust red pepper flakes to taste for desired spiciness.
