Tips & Substitutions
For a lower-carb option, consider replacing croutons with crushed almond flour or a similar low-carb alternative. You can also add some diced mushrooms or spinach for extra flavor and nutrients. If you prefer a creamier texture, substitute the skim milk with unsweetened almond milk or a low-fat yogurt. Make sure to stir the casserole every 5 minutes to ensure even cooking.
Serving Suggestions
Serve this casserole warm, garnished with fresh herbs like parsley for a pop of color. It pairs beautifully with a side salad for a light meal or can be enjoyed alongside steamed broccoli or green beans. For a heartier meal, consider serving with whole grain bread or a slice of your favorite Tomato Cheese Melt.
Storage & Reheating
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the casserole in the microwave for 2-3 minutes or until heated through, stirring halfway. Alternatively, you can reheat in the oven at 350°F for about 15 minutes, covering with foil to prevent drying out.

Frequently Asked Questions
Can I use fresh vegetables instead of frozen peas?
Yes, fresh vegetables can be used in place of frozen peas. Just be sure to cook them slightly before adding to the casserole to ensure they are tender when baked. Fresh peas, diced carrots, or even zucchini would work well in this recipe.
Is this casserole suitable for freezing?
Yes, you can freeze the tuna casserole before baking. Cover it tightly with plastic wrap and then foil. When ready to bake, thaw in the refrigerator overnight and then bake as directed. It’s best to consume within 2-3 months for optimal freshness.
Can I make this casserole without eggs?
Yes, you can substitute the eggs with a flaxseed meal or chia seed mixture (1 tablespoon of flaxseed or chia seeds mixed with 3 tablespoons of water equals one egg). This will help bind the ingredients together while keeping it suitable for those avoiding eggs.
