Ingredients for Low Carb Baked Tilapia with Garlic Butter

Here’s everything you’ll need for this simple yet flavor-packed dish. I always eyeball my ingredients when cooking, but for this recipe, I actually measure because the balance matters:

• 4 tilapia fillets (about 6 oz each) – look for firm, pinkish-white flesh
• 3 tbsp butter, melted (real butter only – it makes all the difference!)
• 3 cloves garlic, minced (or 1½ tsp garlic powder in a pinch)
• 1 tbsp lemon juice – fresh squeezed if you can
• 1 tsp dried parsley (or 1 tbsp fresh if you’ve got it)
• ½ tsp salt (I use sea salt for extra flavor)
• ¼ tsp black pepper – freshly cracked if possible
• ¼ tsp paprika (the smokier the better!)

See? Nothing fancy – just good, honest ingredients that work magic together!

How to Make Low Carb Baked Tilapia with Garlic Butter

Okay, let’s get cooking! This recipe is so simple, but I’ve learned a few tricks over the years to make it absolutely perfect every time. Follow these steps, and you’ll have flaky, buttery tilapia that’ll make your whole kitchen smell amazing.

Step 1: Preheat and Prepare

First things first – crank that oven to 375°F (190°C). While it’s heating up, grab your baking sheet and line it with parchment paper. I’m obsessed with parchment because it makes cleanup a breeze – no scrubbing stuck-on fish later! If you don’t have any, a quick spray of cooking oil will do in a pinch.

Step 2: Mix the Garlic Butter

Now for the good stuff! Melt your butter (careful not to burn it – 30 seconds in the microwave usually does the trick for me). In a small bowl, mix that golden goodness with your minced garlic, lemon juice, parsley, salt, pepper, and paprika. Stir it really well – you want all those flavors to get friendly before they meet the fish. Pro tip: let this mixture sit for 5 minutes if you can – it helps the garlic flavor really bloom!

Step 3: Bake the Tilapia

Place your tilapia fillets on the prepared baking sheet (make sure they’re not touching – we’re not making fish pancakes here!). Now, grab a pastry brush or spoon and slather that garlic butter all over each fillet. Don’t be shy – get both sides! Pop them in the oven for 12-15 minutes. You’ll know they’re done when the edges start getting golden and the fish flakes easily with a fork. And please – don’t overcook it! Nothing worse than dry tilapia. If it flakes with just a little pressure, it’s perfection.

See? Told you it was easy! Now go enjoy your masterpiece – you’ve earned it!

Tips for Perfect Low Carb Baked Tilapia with Garlic Butter

After making this recipe more times than I can count, here are my foolproof tricks for tilapia that’ll have everyone begging for seconds:

• Fresh is best: Real garlic cloves beat powder every time – the flavor just pops!
• Watch the clock: Set a timer for 12 minutes – tilapia goes from perfect to rubbery fast
• Cheese lover? Sprinkle Parmesan over the top before baking for a golden, crispy crust
• Pat dry: Blot fillets with paper towels first – helps the butter stick better
• Butter boost: Double the garlic butter if you’re feeling extra indulgent (no judgment here!)

Trust me, these little touches make all the difference between good and “oh wow” good!

Serving Suggestions for Low Carb Baked Tilapia

This garlic butter tilapia plays so well with others! My favorite way to serve it? Piled high with roasted asparagus or garlicky sautéed spinach. For crunch, add a simple arugula salad with lemon vinaigrette. On lazy nights, I just grab some steamed broccoli from the freezer – still delicious!

Ingredient Substitutions and Notes

No fresh garlic? No problem! Use 1½ tsp garlic powder instead of cloves – just mix it right into the melted butter. Out of lemon juice? A splash of white wine or chicken broth works in a pinch. And if you’re dairy-free, ghee or olive oil can replace butter (though I’ll miss that rich flavor!). One important note – frozen tilapia works fine, but thaw it completely and pat it dry first, or you’ll end up with soggy fish.

Storage and Reheating Instructions

Leftovers? No worries! Store cooled tilapia in an airtight container in the fridge for up to 2 days. When reheating, go low and slow – 30 seconds in the microwave at 50% power does the trick without turning it rubbery. For extra moisture, place a damp paper towel over the fish while reheating. So simple!

Nutritional Information for Low Carb Baked Tilapia with Garlic Butter

Frequently Asked Questions

Can I use frozen tilapia for this recipe?
Absolutely! Just make sure to thaw it completely in the fridge overnight first. I always pat mine dry with paper towels – frozen fish tends to hold more moisture, and we don’t want soggy results. The texture might be slightly less firm than fresh, but it’ll still taste delicious with that garlic butter magic.

How can I add more flavor to my baked tilapia?
Oh, I love playing with this! Try adding a pinch of red pepper flakes to the butter for heat, or swap regular paprika for smoked paprika. Sometimes I’ll toss in some lemon zest along with the juice – really brightens everything up. And if you’re feeling fancy, a sprinkle of capers or chopped sun-dried tomatoes before baking takes it next-level.

What’s the best way to know when the fish is done?
Here’s my foolproof test: gently poke the thickest part with a fork. If it flakes easily and looks opaque all the way through, it’s perfect. Don’t wait for it to look dry – tilapia keeps cooking a bit after you pull it from the oven. Remember – 12-15 minutes is usually the sweet spot!
