In a medium bowl, toss the shrimp with olive oil, smoked paprika, garlic powder, salt, pepper, and lemon juice. Let marinate for 10–15 minutes.
Prepare the creamy garlic sauce by melting butter in a saucepan over medium heat. Add garlic and cook for 1 minute until fragrant.
Stir in the flour and cook for another minute to form a smooth roux.
Slowly whisk in the milk, stirring continuously until the sauce thickens, about 3–4 minutes.
Add Parmesan cheese, salt, pepper, and optional red pepper flakes or lemon zest. Stir until smooth, then remove from the heat.
Toss the asparagus with olive oil, salt, and pepper. Grill over medium-high heat for 4–6 minutes until crisp-tender with light char marks.
Grill the shrimp for 2–3 minutes per side until opaque and lightly charred.
Divide the cooked rice among serving bowls.
Arrange the grilled asparagus and shrimp over the rice.
Generously drizzle the Grilled Shrimp Bowl with Asparagus & Creamy Garlic Sauce with the warm garlic Parmesan sauce.
Garnish with chopped parsley, extra Parmesan, and fresh lemon wedges before serving.
