What You’ll Need (Ingredients)

• Salmon: 4 skin-on fillets (4–5 oz each)
• Green beans: 1 lb trimmed (fresh or thawed frozen)
• Olive oil or avocado oil: 2 tbsp total
• Lemon: 1, zested and halved
• Garlic: 3 cloves, minced (or 1 tsp garlic powder)
• Fresh parsley: 2 tbsp, chopped (optional but nice)

Blackening Spice Mix:

• 1.5 tsp smoked paprika
• 1 tsp chili powder
• 1 tsp onion powder
• 1 tsp garlic powder (skip if using fresh in beans)
• 1/2 tsp dried thyme
• 1/2 tsp dried oregano
• 1/2 tsp ground black pepper
• 1/2 to 3/4 tsp kosher salt
• 1/4 tsp cayenne (bump to 1/2 tsp if you like it fiery)

Optional Add-Ons (to stay under 400 calories):

• 1 tsp butter per fillet (swap for 1 tsp oil if dairy-free)
• Lemon wedges for serving

Let’s Get Cooking – Instructions

1. Prep the spice mix: In a small bowl, combine smoked paprika, chili powder, onion powder, garlic powder, thyme, oregano, pepper, salt, and cayenne. Set aside.
2. Dry the salmon like you mean it: Pat the fillets thoroughly with paper towels. Dry fish equals better crust.

   Squeeze on a little lemon juice, then rub 1 tbsp oil over the fillets.

3. Season with intent: Coat the tops of the fillets generously with the blackening spice mix. Press it in so it sticks. Don’t be shy.
4. Heat the pan: Use a large cast-iron or heavy skillet.

   Heat 1 tbsp oil over medium-high until it shimmers. You want it hot, not smoking.

5. Sear the salmon: Place fillets skin-side up first for 2–3 minutes to build that spicy crust. Flip carefully, reduce heat to medium, and cook skin-side down 3–4 minutes until just cooked through (125–130°F internal).

   Remove to a plate and rest.

6. Sauté the beans: In the same pan, toss in green beans, minced garlic, and a pinch of salt and pepper. Cook 4–6 minutes, stirring occasionally, until bright green and tender-crisp. Add lemon zest and a squeeze of lemon to finish.

   If the pan is dry, splash 1–2 tbsp water to steam.

7. Optional butter baste: For a restaurant vibe, melt 1 tsp butter in the pan and spoon over the salmon for 20 seconds. Flavor skyrockets; calories barely move.
8. Plate it smart: Portion beans into 4 meal prep containers. Top each with one salmon fillet.

   Sprinkle chopped parsley and add lemon wedges. Flex.

Storage Instructions

• Fridge: Store in airtight containers up to 4 days. Keep lemon wedges separate to avoid bitterness.
• Freezer: Salmon freezes well (up to 2 months).

  Green beans can get softer but still fine. Thaw overnight in the fridge.

• Reheat: Microwave 60–90 seconds at 60–70% power. Or rewarm in a covered skillet over low heat with a splash of water.

  Don’t overcook unless you enjoy sawdust salmon.

Why This is Good for You

• Protein for satiety: Salmon delivers 30–35g protein per serving, stabilizing hunger and supporting lean muscle. FYI, that’s what keeps cravings quiet.
• Omega-3s on deck: EPA and DHA support heart, brain, and anti-inflammatory health. Big benefits, zero extra effort.
• Low-calorie veggies: Green beans bring fiber, vitamin C, and minerals for under 50 calories per cup.

  Crunchy, clean, and not boring.

• Spice advantage: Blackening spices add flavor without extra calories or sugar. Metabolism boost? Minor.

  Flavor boost? Major.

Pitfalls to Watch Out For

• Wet fish, weak crust: If you don’t pat the salmon dry, the spice won’t sear. You’ll steam it.

  Sad.

• Overcooking: Pull at 125–130°F. Resting finishes the job. Dry fish = meal prep morale killer.
• Too much salt: The spice mix already has salt.

  Taste your beans before adding more.

• Burned spices: If the pan starts smoking hard, lower heat. Char is great; bitter ash is not.
• Calorie creep: A “little” extra oil can become 100+ calories fast. Measure, don’t guess—IMO the difference adds up weekly.
