Preparation instructions
Prepare the chicken hearts
1Rinse the chicken hearts under cold running water to remove any residual blood. Pat them dry with paper towels. Trim any fat or connective tissue for a cleaner taste and appearance. This helps improve texture and prevents any unpleasant flavors.
Marinate with lemon and garlic
2In a bowl, combine the juice and zest of one lemon, minced garlic, salt, and black pepper. Toss the cleaned chicken hearts in this mixture and let them marinate for 15 minutes at room temperature. Marinating infuses flavor and tenderizes the hearts.
Sauté onions and chicken hearts
3Heat the olive oil in a large skillet or pan over medium heat. Add the sliced onions and cook for 5 minutes until softened and fragrant. Add the marinated chicken hearts and cook for another 5-7 minutes, stirring occasionally until they start to brown lightly. This seals in flavor.
Add broth and slow cook
4Pour in the chicken broth, scraping any browned bits from the bottom of the pan for extra flavor. Reduce the heat to low, cover, and simmer gently for 45 minutes. Slow cooking tenderizes the hearts and develops rich flavors.
Check doneness with safe temperature
5Use a meat thermometer to check the internal temperature of the chicken hearts, which should reach at least 74°C (165°F) for safe consumption. The hearts should be tender and cooked through, not rubbery.
Finish with fresh lemon and parsley
6Just before serving, squeeze the juice of the second lemon over the hearts and sprinkle chopped parsley for a fresh, bright finish. Adjust salt and pepper to taste.
Cooking Tips
1Avoid cross-contamination by using separate cutting boards and utensils for raw chicken hearts and other ingredients.
2If you don’t have a slow cooker, you can use a heavy pan with a tight-fitting lid, cooking gently on the lowest heat possible.
3For more flavor, add a pinch of smoked paprika or chili flakes during the sauté step.
4Always wash your hands thoroughly after handling raw poultry to ensure food safety.

FAQ
How do I know when chicken hearts are fully cooked?
Chicken hearts are fully cooked when they reach an internal temperature of 74°C (165°F). They should be tender, not rubbery. Using a meat thermometer is the best way to ensure safety.
Can I use frozen chicken hearts for this recipe?
Yes, you can use frozen chicken hearts. Thaw them completely in the refrigerator before cooking, and rinse well to remove any ice crystals or residue.
What if I don’t have a slow cooker or thermometer?
You can cook the hearts gently on the stove over low heat, ensuring they simmer covered for 45 minutes. While a thermometer is best for safety, cooking gently and thoroughly should produce a safe and tender result.
Can I use other citrus fruits instead of lemon?
Absolutely! Lime or orange can be used for a different but delightful citrus flavor while maintaining the tenderizing effect.
