Start by heating your large skillet over medium heat until warm.
Add the butter to the skillet, allowing it to melt and shimmer gently. You’ll hear a soft sizzling sound as it coats the pan.
Toss in the minced garlic and stir quickly. Cook for about 30 seconds until fragrant and golden, but be careful not to let it burn—this keeps the aroma bright and nutty.
Add the frozen peas directly into the skillet. Stir well to coat them with the garlic butter mixture. Cook for 2-3 minutes, until the peas are heated through and start to pop softly, releasing a sweet aroma and vibrant green color.
Season with a pinch of salt and freshly cracked pepper. Squeeze in a little lemon juice if you like a bright, tangy note. Stir everything together and cook for another minute to meld the flavors.
Remove from heat and let sit for a minute. The sauce will thicken slightly, coating the peas with a glossy, fragrant layer. Serve immediately as a cozy, flavorful side dish.
