Dice the onion and mince the garlic, setting them aside. Cut the chicken thighs into 1-inch chunks and pat them dry with paper towels—this helps them brown better. In a small bowl, combine the smoked paprika, Italian seasoning, red pepper flakes, salt, and black pepper. Rinse the rice under cold water until the water runs clear, then set aside. Have the sun-dried tomatoes julienned, artichoke hearts drained and halved, capers drained, and parmesan freshly grated and ready to go.
Set your Instant Pot to sauté mode and add the olive oil. Once hot, add the diced onions and cook for 4 minutes, stirring occasionally, until they begin to soften and become translucent. Add the minced garlic and cook for just 30 seconds more—garlic burns quickly, so timing is crucial here. I like to watch the garlic carefully at this stage; you want its aroma to bloom without it turning bitter.
Turn off the sauté function and add the chicken chunks and the spice mixture from Step 1 (paprika, Italian seasoning, red pepper flakes, salt, and pepper). Stir well to coat the chicken evenly with the spices. Pour in the chicken stock and use a wooden spoon to scrape the bottom of the pot, releasing any browned bits—these add incredible depth of flavor. Add the lemon juice and stir to combine.
Sprinkle the rinsed rice evenly over the liquid without stirring—this technique helps the rice cook evenly and absorb the flavors from the broth below. Close the Instant Pot lid and set the valve to sealing position. Cook on high pressure for 3 minutes. I find that this short cook time keeps the chicken tender while allowing the rice to absorb all the aromatic broth.
Allow the pot to sit undisturbed for 10 minutes to let pressure release naturally—this prevents the rice from becoming mushy. After 10 minutes, carefully turn the valve to venting position to release any remaining steam, then open the lid. Gently stir in the sun-dried tomatoes, artichoke hearts, capers, and freshly grated parmesan cheese from Step 1, folding them in to distribute evenly without breaking up the rice.
Divide the Mediterranean chicken and rice mixture into serving bowls. Top each portion with a generous handful of fresh chopped parsley and arrange a few thin lemon slices on top for brightness and visual appeal. The fresh herbs and lemon add a vibrant contrast to the warm, savory rice dish.
