Bring a large pot of salted water to a boil and add the rotini pasta. Cook until the noodles are slightly softer than al dente so they stay tender once chilled. Drain the pasta and rinse under cold water to stop the cooking process. Let it cool completely before mixing with other ingredients.

In a small skillet over medium heat, melt the 2 tablespoons of butter. Continue heating, stirring constantly, until the butter begins to turn a light golden-brown, small brown bits form at the bottom, and it smells nutty (about 3-5 minutes). (This is the secret brown butter technique.)

Immediately remove the skillet from the heat to prevent burning. Add the fine dried herbs to the hot brown butter and stir well to infuse the flavors. Let the mixture cool slightly.

In a large mixing bowl, whisk together the mayonnaise, sour cream/Greek yogurt, vinegar, sugar, salt, pepper, and garlic/onion powder.

Add the slightly cooled brown butter and herb mixture to the other dressing ingredients and whisk thoroughly until smooth and fully combined. This secret ingredient will lend a rich depth and an elusive, irresistible flavor to your dressing.

While the pasta cools, chop all the vegetables. Slice the cherry tomatoes in halves, dice the cucumber, chop the bell peppers, shred the carrot, finely chop the onion, and thaw the peas if you haven’t already. Fresh veggies add a crisp bite and extra color.

Grab a large mixing bowl and add the cooled pasta. Pour in the dressing and toss to coat the noodles evenly. Gently fold in the chopped vegetables until every piece is covered in the creamy sauce.

Cover the bowl tightly and refrigerate the salad for at least eight hours or overnight if possible. This helps the flavors blend together and gives the salad a richer taste. Give it a good stir before serving to refresh the dressing and make sure every bite is creamy and delicious.
