Heat 1 tablespoon of olive oil in a large skillet over medium-high heat.
Add the chicken pieces to the skillet and season with salt, black pepper, and paprika.
Cook the chicken for 6-8 minutes, stirring occasionally, until fully cooked and lightly browned. Remove the chicken from the skillet and set aside.
In the same skillet, add the remaining 1 tablespoon of olive oil and minced garlic. Sauté for 30 seconds until fragrant.
Add the broccoli florets to the skillet and stir-fry for 3-4 minutes until they are bright green and slightly tender.
Pour in the chicken broth and soy sauce, then cover the skillet with a lid.
Steam the broccoli for an additional 3 minutes until tender-crisp.
Return the cooked chicken to the skillet, add crushed red pepper flakes and lemon juice, and stir everything together.
Cook for another 2 minutes to combine flavors and heat through.
Remove from heat and serve immediately.
