In a large skillet, melt 2 tablespoons of butter over medium heat until it begins to foam slightly.
Once the butter is melted, add the minced garlic and red pepper flakes. Sauté for approximately 1 minute, stirring constantly, until the garlic is fragrant but not browned.
Increase the heat to medium-high and add the shrimp to the skillet. Cook for 2-3 minutes, stirring gently, until the shrimp are pink and opaque throughout. Be careful not to overcook them.
Remove the cooked shrimp from the skillet and transfer them to a plate; set aside.
In the same skillet, add the remaining 2 tablespoons of butter. Once melted, add the halved cherry tomatoes and chopped spinach. Sauté for 2-3 minutes, until the tomatoes begin to soften and the spinach wilts beautifully.
Gradually stir in the cooked rice, ensuring it's well combined with the vegetables and butter mixture, breaking up any clumps.
Return the shrimp to the skillet, followed by the lemon juice, salt, and pepper. Gently stir to combine all ingredients, cooking for an additional 2 minutes to warm through.
Remove the skillet from heat and sprinkle freshly chopped parsley on top for a pop of color and flavor before serving.
Notes
For a rustic appeal, serve the dish directly in the skillet, allowing guests to help themselves.
