FAQ
Healthy Tuna Meatballs Recipe Substitutions and Variations
- If you dont have tuna, you can use canned salmon or even shredded chicken for a twist.
- You can swap the egg with 1 tbsp of ground flaxseed mixed with 3 tbsp water, just stir it and let it sit for 5 minutes.
- If whole wheat breadcrumbs arent available, try using gluten-free breadcrumbs or crushed oats, they work just fine.
- Instead of Parmesan cheese you might use Pecorino Romano or a sprinkle of nutritional yeast if youre avoiding dairy.
- For that lemon juice, a squeeze of lime juice or even a bit of white wine vinegar can be a good alternative.
Pro Tips
1. Try chilling the mixture in the fridge for like 20 minutes before forming the meatballs so they hold together better and are easier to shape without falling apart.
2. Wet your hands a bit with water before rolling the meatballs, this really helps to keep the mix from sticking and makes the process neater.
3. If you’re into a little extra spice, toss in a pinch of dried chili flakes or cayenne pepper to give the meatballs a kick without overpowering the tuna flavor.
4. Let the meatballs rest a few minutes after baking so the inside finishes cooking and the flavors get a chance to meld together – it honestly makes a difference in taste.
