Place a small skillet over medium-low heat and add the butter. Let it melt gently, watching as it begins to foam and releases a nutty aroma, about 2 minutes.
Add the thinly sliced garlic to the skillet and sauté, stirring constantly, until it turns golden and fragrant, about 1 minute. The garlic should sizzle softly, filling the air with a warm aroma.
Gently toss in the fresh peas and stir to coat them in the butter and garlic. Cook for about 2-3 minutes, until the peas turn a brighter green and feel tender but still have a slight crunch. They should make a slight popping sound as they cook.
Squeeze half a teaspoon of lemon juice over the peas, then season with a pinch of salt and freshly ground black pepper. Stir everything together to evenly distribute the flavors and brighten the dish.
Cook for another minute, allowing the flavors to meld and the peas to remain vibrant and crisp. Once ready, remove the skillet from heat.
Transfer the peas to a serving dish, and if desired, garnish with a small herb sprinkle like dill or mint for extra freshness. Serve immediately while warm, enjoying the fragrant, buttery, garlicky peas.
