1-First Step: Make the creamy dressing Grab a small bowl and stir together the 1/3 cup sour cream, 1 tablespoon mayonnaise, 1 tablespoon white vinegar, plus salt and pepper to taste. Mix until smooth and creamy. This dressing should taste a little tangy and well seasoned, because it has to coat all those peas and still hold up after chilling. If you like a slightly sharper flavor, add a tiny extra splash of vinegar. If you want it richer, you can lean a little heavier on the mayo. The goal is a dressing that tastes good on its own, since chilled salads often mellow out a bit after resting.

2-Second Step: Prep the peas and other mix-ins Place the 4 cups frozen green peas in a colander and thaw them until they are almost totally thawed. You do not want to cook them. Just let them soften enough to mix easily while keeping that sweet pea crunch people love. If they are too wet, pat them dry with paper towels so the dressing does not get watered down later. While the peas thaw, cook the 8 slices bacon until crisp, then drain and chop it. Slice the 1/2 small red onion very thin, cube the 6 ounces cheddar or American cheese, and mince the 3 tablespoons fresh parsley.

3-Third Step: Coat the peas with part of the dressing Add the peas to a large mixing bowl. Spoon in about two-thirds of the dressing and stir gently until the peas are coated. Do not mash them. You want each pea covered in creamy dressing without losing that fresh, springy look. This step matters because peas soak up dressing as they chill. Starting with most of the dressing gives the salad flavor right away, while saving some for later helps you fix dryness before serving. If you are making this for a gathering, this is one of those tiny details that saves the whole dish.

4-Fourth Step: Fold in the bacon, onion, cheese, and parsley Now add the chopped bacon, sliced red onion, cubed cheese, and minced parsley. Stir gently until everything is combined. The key word here is gently. If you stir too hard, the peas can break apart and the cheese can smear into the dressing. At this stage, taste the salad. Add a little more salt or pepper if needed. If the flavor feels a bit flat, another tiny splash of vinegar can wake it up. The bacon adds salt, so wait before over-seasoning.

5-Fifth Step: Chill the salad Cover the bowl and refrigerate it for 2 to 4 hours. This resting time gives the flavors a chance to blend. The onion softens slightly, the dressing settles in, and the salad tastes more rounded after chilling. If you are short on time, you can serve it sooner, but the texture and flavor are usually better after a little rest. For make-ahead planning, this salad can be prepared up to two days in advance. If you do that, keep the bacon separate until serving so it stays crisp.

6-Final Step: Finish and serve When you are ready to serve, take the bowl out of the fridge and stir in the remaining dressing as needed. Some peas will absorb more dressing than others, so do a quick check before sending it to the table. If it looks dry, add the rest of the dressing or a small spoonful more. Sprinkle extra parsley over the top for a fresh finish. This salad tastes especially good after sitting at room temperature for about 30 minutes, which helps the flavors open up a little. That makes it a great side dish for Easter brunch, spring cookouts, or any meal where you want something cool and colorful.
