Thaw and peel 2 lbs of shrimp, leaving the tail on. Place them in a bowl with the juice of half a lemon, Lake Shore seasoning (or Italian seasoning), paprika, red pepper flakes, ½ teaspoon salt, and ¼ teaspoon pepper. Set aside while the rice cooks.
Melt 2 tablespoons of butter in a large skillet, add shallot and garlic then saute over medium heat until fragrant and translucent, about 3 minutes.
Add the rice to the skillet and toast the rice while frequently stirring until the rice is lightly toasted 1 to 2 minutes.
Stir in the stock, juice of half a lemon, ½ teaspoon salt, and pepper. Cover the pan. Bring the pan to a boil then reduce to a simmer, and cook for 12 to 15 minutes, until liquid is mostly absorbed and rice is fluffy.
Add the shrimp and marinade, cover, and continue to cook for 5 minutes until the shrimp is no longer opaque.
Garnish with parsley and more lemon juice if desired. Serve immediately and enjoy!
