Baked Salmon with Spinach Recipe FAQs
What should I look for when selecting salmon?
Absolutely! When choosing your salmon fillet, look for bright pink flesh that’s free from dark spots or discoloration. Fresh salmon should feel firm to the touch and should have a clean, ocean-like smell, not a strong fishy aroma.
How should I store leftovers from my Baked Salmon with Spinach?
Very good question! Store your leftovers in an airtight container in the fridge for up to 2 days. To reheat, gently warm it in the microwave or oven. If using the oven, cover it with aluminum foil to keep the salmon moist as it reheats.
Can I freeze my Baked Salmon with Spinach?
Of course! You can freeze individual portions in airtight containers for up to 3 months. To freeze, ensure the salmon is completely cooled, then wrap each portion tightly or place it in freezer-safe bags. When ready to enjoy, simply thaw overnight in the fridge before reheating them in the oven until warmed through.
How do I avoid overcooking the salmon?
To make sure you don’t overcook your salmon, aim for an internal temperature of 63°C (145°F). Using a meat thermometer is the best way to check. Remember, the salmon will continue to cook slightly after removing it from the oven, so taking it out right when it reaches that temperature will keep it flaky and moist.
Is this recipe suitable for someone with dairy allergies?
Yes, this Baked Salmon with Spinach can easily be adapted for dairy allergies! Simply swap out the sour cream and mozzarella cheese for suitable dairy-free alternatives, such as Greek yogurt or a plant-based cheese.
What can I do if my spinach mixture is too watery?
If your spinach mixture turns out too watery, don’t worry! To fix this, try draining the spinach thoroughly before adding it to the onion and garlic mixture. You can even use a clean kitchen towel to squeeze out any excess water. Additionally, cooking the spinach a bit longer can help evaporate some moisture before combining it with the sour cream.
