- Dry mustard: 1 1/2 teaspoons adds a tangy warmth that enhances the seasoning blend.
- Salt: 1 teaspoon to balance and bring out the savory notes.
- Black pepper: 1 teaspoon for a fresh, sharp ground spice hit.
- Unsalted butter: 6 tablespoons, divided, provide a rich and creamy base for sautéing and sauce.

How to Make Deviled Kidneys Recipe
Step 1: Clean and Prepare the Kidneys
Start by carefully trimming and cleaning the deer kidneys. Cut each half into 3 or 4 pieces, which ensures they cook evenly and absorb the seasoning beautifully.
Step 2: Sear the Mushrooms
In a hot pan, melt 3 tablespoons of unsalted butter and toss in the mushrooms. Let them brown until they develop a lovely caramelized color and rich flavor. Then remove and set aside; this step enhances their texture and creates a delicious base for the sauce.
Step 3: Mix the Spice Coating
Combine the flour, cayenne, dry mustard, salt, and black pepper in a bowl. This spice blend is the heart of the “deviled” element, giving the kidneys that famous fiery edge.
Step 4: Coat and Brown the Kidneys
Dust the kidney pieces evenly in the flour mixture. In the same pan used for mushrooms, heat the remaining 3 tablespoons of butter. Brown the kidneys until they achieve a golden crust, pressing down slightly with a spatula if needed to ensure good contact and caramelization. Remove the kidneys and slice them to your preferred size if you want smaller bites.
Step 5: Combine and Finish Cooking
Return the browned kidneys and mushrooms back to the pan. Add a splash of Worcestershire sauce and the stock, then shake the pan gently to mix everything. Let this cook together for a couple of minutes to meld flavors and thicken the sauce slightly.
Step 6: Serve on Toast
Pile the tender kidneys and mushrooms onto slices of hot buttered toast. Boil down the sauce for a few extra minutes until it beautifully coats the toast and kidney mixture, then pour it over everything. Serve this while it’s sizzling warm for the best experience.
How to Serve Deviled Kidneys Recipe

Garnishes
Fresh herbs like parsley or chives scattered on top add a vibrant pop of color and freshness that balances the spice. A squeeze of lemon can also brighten the dish wonderfully, cutting through the richness with light acidity.
Side Dishes
This Deviled Kidneys Recipe pairs beautifully with simple sides such as mashed potatoes or buttered peas. The creamy textures complement the sharp, spicy flavors perfectly, creating a more substantial and comforting meal.
Creative Ways to Present
For an elegant twist, serve the deviled kidneys over toasted baguette slices as an appetizer at dinner parties. Alternatively, spoon the kidneys and sauce atop a bed of creamy polenta or buttery grits to elevate the dish into hearty, soul-warming fare.
Make Ahead and Storage
Storing Leftovers
Deviled kidneys taste best fresh, but you can refrigerate leftovers in an airtight container for up to two days. To preserve flavor and texture, reheat gently on the stovetop rather than microwaving.
Freezing
Freezing is not ideal for this dish because the texture of the kidneys and sauce may suffer. However, if needed, place cooled leftovers in a freezer-safe container and consume within one month.
Reheating
When reheating your leftovers, warm gently in a pan over low heat to avoid overcooking the kidneys, stirring occasionally to redistribute the sauce evenly. Add a splash of stock or water if the sauce looks too thick or dry.
FAQs
Can I use other types of kidneys instead of deer?
Absolutely! Lamb or calf kidneys are excellent substitutes if deer kidneys are not available. Just make sure to prepare and clean them thoroughly before cooking.
Is it necessary to include mushrooms?
Mushrooms are optional but highly recommended as they add wonderful earthiness and texture contrast. If you prefer a simpler version, feel free to omit them.
How spicy is the Deviled Kidneys Recipe?
The cayenne pepper and dry mustard provide a pleasant warmth and bite without overwhelming heat. You can adjust the cayenne quantity to suit your spice preference.
What type of toast works best for serving?
A sturdy, buttered white or sourdough bread is best as it soaks up the delicious sauce without falling apart. Serving on thick-cut toast ensures a perfect bite every time.
Can I make this dish vegetarian?
This recipe centers on kidneys, so it’s not naturally vegetarian. However, transforming it with hearty mushrooms and a rich spiced sauce can create a similar flavor profile for vegetarians without using meat.
Final Thoughts
Nothing beats the unique, comforting flavors of this Deviled Kidneys Recipe when you’re looking for something both classic and surprising.
