Colorado’s Rocky Mountain Oysters

Despite the name, Rocky Mountain Oysters are not seafood; they’re deep-fried bull testicles. This dish is a novelty in some parts of Colorado and is often served at festivals and events. Colorado, like many states, has a diverse food scene influenced by various cultures and its unique geography. While the idea of Rocky Mountain Oysters may be adventurous for some, here’s a basic recipe for preparing this unique dish.


  • 1 pound (about 450 grams) bull testicles
  • 2 cups buttermilk
  • 1 cup all-purpose flour
  • Salt and pepper to taste
  • Oil for frying


  1. Prepare the Testicles:
    • Start by rinsing the bull testicles under cold running water. Remove the tough outer membrane, being careful not to damage the delicate inner meat.
  2. Soak in Buttermilk:
    • Place the prepared testicles in a bowl and cover them with buttermilk. Let them soak for at least a couple of hours or overnight in the refrigerator. This helps to tenderize the meat.
  3. Dredge in Flour:
    • In a separate bowl, mix the all-purpose flour with salt and pepper. Remove the testicles from the buttermilk and dredge them in the seasoned flour, coating them thoroughly.
  4. Heat the Oil:
    • Heat oil in a deep fryer or a large, deep skillet to around 350°F (175°C).
  5. Fry the Testicles:
    • Carefully place the coated testicles into the hot oil. Fry them for 3-5 minutes or until they are golden brown and crispy.
  6. Drain and Serve:
    • Use a slotted spoon to remove the fried testicles from the oil and place them on paper towels to drain excess oil.
  7. Serve Hot:
    • Rocky Mountain Oysters are typically served hot and are often accompanied by dipping sauces like cocktail sauce, horseradish, or aioli.
  8. Optional: Seasoning:
    • Feel free to experiment with additional seasonings or spices in the flour mixture to add flavor.

Remember, this dish is an acquired taste, and its popularity is often tied to its novelty. It’s essential to source the ingredients from reputable sources and follow proper food safety practices.
