Description

A protein-packed, omega-3 rich savory cake that combines the irresistible appeal of tuna with nutritious beans and quinoa for a treat that’s more like a healthy meal.

Prep Time: 15 minutes | Cook Time: 25-30 minutes | Total Time: 45 minutes | Makes: 8-10 slices Creamy dog food casserole with vegetables and herbs, served on a white plate.

Ingredients

Scale

1 can (5 oz) tuna in water, drained (never oil or salt—check that label!)
1 cup cooked white beans, mashed (rinse canned beans thoroughly to remove sodium)
½ cup cooked quinoa (completely safe for dogs and packed with amino acids)
¼ cup shredded carrots (fresh grated works best)
1 large egg (room temperature mixes better)
2 tbsp chopped fresh parsley (flat-leaf or curly, never spring parsley)
1 tbsp extra virgin olive oil (for that golden crust)

Instructions

Preheat your oven to 350°F and grease a small cake pan with coconut oil—trust me, this prevents sticking disasters.
In a large mixing bowl, flake the drained tuna and combine with mashed white beans, cooked quinoa, shredded carrots, egg, and chopped parsley until your dog starts begging from the amazing smell.
Mix well until all ingredients are evenly incorporated—about 2 minutes of stirring should create the perfect binding.
Transfer the protein-packed mixture into your greased cake pan and smooth the top with a spatula.
Drizzle olive oil over the top for that gorgeous golden finish (Amber’s favorite part).
Bake for 25-30 minutes until set and lightly browned—watch carefully after 20 minutes.
Let cool completely before slicing and serving (if your pup can wait that long)—hot fish can burn sensitive mouths.

Notes:

Always let cool completely before serving—the cake will be very hot inside
Amber prefers thin slices, but some dogs like chunkier pieces
The fishy smell is normal and exactly what drives dogs crazy for this treat

Storage Tips:

Store in airtight container in refrigerator for up to 4 days
Wrap well to contain the fish aroma—it will take over your fridge otherwise
Perfect for freezing in individual slices—just thaw when ready to serve
Toss if it develops any off smells or slimy texture

What Makes This Recipe Special:

This savory cake delivers complete nutrition with omega-3 fatty acids from tuna for coat health, plant-based protein from white beans for muscle support, and essential amino acids from quinoa for overall wellness. The combination creates a slice-able treat that’s more satisfying than traditional biscuits and provides genuine nutritional benefits.
