Step‑by‑Step Instructions for Baked Tuna Meatballs
Step 1: Sauté the Aromatics
Heat 2 tablespoons of olive oil in a skillet over medium heat. Add 1 small diced onion and 2 minced garlic cloves, sautéing them for about 1 minute or until they’re fragrant and slightly translucent. Keep an eye on the heat to avoid burning; you want them to soften and turn golden. Once ready, add 2 cups of chopped baby spinach to the pan and sauté until wilted, around 1-2 minutes.
Step 2: Cool the Vegetable Mixture
After sautéing the spinach, remove the skillet from heat and let the vegetable mixture cool for a few minutes. This step is important because adding hot veggies to the meatball mixture could affect the texture. While it cools, preheat your oven to 400°F (200°C). The oven will need time to reach this temperature, ensuring your Baked Tuna Meatballs cook evenly.
Step 3: Combine Ingredients
In a large mixing bowl, drain 2 cans of tuna and break it up with a fork. Add the cooled vegetable mixture, along with 1/2 cup of almond flour, 2 eggs, 1/4 cup of mayonnaise, 2 tablespoons of lemon juice, a handful of chopped fresh parsley, 1 tablespoon of fresh dill, and salt and pepper to taste. Mix everything together until well combined, making sure the ingredients are evenly distributed.
Step 4: Shape the Meatballs
Using a cookie scoop or your hands, shape the mixture into uniform balls, each about 1-2 inches in diameter. This helps ensure even cooking for all your Baked Tuna Meatballs. Place the shaped balls on a parchment-lined baking sheet, leaving space between them to allow for expansion during baking. You should be able to get around 12-16 meatballs, depending on how big you make them.
Step 5: Bake to Perfection
Once all the meatballs are shaped and arranged, pop them in the preheated oven. Bake for 20-25 minutes, or until they are golden brown on the outside and cooked through. To test for doneness, insert a toothpick into the center; it should come out clean. The aroma will fill your kitchen, indicating they are ready to serve and enjoy!

Baked Tuna Meatballs Recipe FAQs
How do I choose the best canned tuna for my meatballs?
Absolutely! When selecting canned tuna, look for tuna packed in water or olive oil, as this will provide the best flavor and moisture. Opt for high-quality brands that use sustainable fishing practices to ensure you’re getting a fresh product. Check for any dark spots on the tuna, which can indicate spoilage.
What’s the best way to store leftover meatballs?
Very! You can store cooked Baked Tuna Meatballs in an airtight container in the fridge for up to 3-4 days. Just make sure they cool down before putting them in the container to maintain freshness. If you want to keep them longer, consider freezing them for up to 3 months.
How do I freeze Baked Tuna Meatballs properly?
Of course! To freeze, shape your meatballs and place them on a parchment-lined baking sheet in a single layer. Pop the entire sheet into the freezer for about 1-2 hours until they’re firm. After that, transfer them to a freezer-safe bag or container. Label with the date, and they can be enjoyed for up to 3 months. When ready to eat, thaw in the fridge overnight and reheat as directed.
My meatballs turned out too soft; what should I do?
Don’t worry! If your Baked Tuna Meatballs are too soft, it likely needs more binder. Simply add an extra 1-2 tablespoons of almond flour or a suitable alternative to the mixture and mix well. This will help absorb excess moisture and give your meatballs a firmer texture. Another trick is ensuring the sautéed vegetables are completely cooled before incorporating them into the mixture, as hot ingredients can make them mushier.
Can I make Baked Tuna Meatballs egg-free?
Absolutely! If you need to avoid eggs, you can use a chia seed or flaxseed meal substitute. To do this, mix 1 tablespoon of chia seeds or ground flaxseed with 2.5 tablespoons of water, and let it sit for about 5 minutes until it forms a gel-like consistency. This acts as a great binding agent to hold your meatballs together without eggs.
Are Baked Tuna Meatballs safe for my pets?
Very! Your furry friends can enjoy these meatballs in moderation, but it’s essential to skip any harmful ingredients like onion or garlic. Instead, you can share plain meatballs made from tuna, without spices, and they should love it! Always consult your vet before introducing new foods to your pet’s diet.
