Shopping List – Ingredients
- Raw shrimp (1.5 lbs, peeled and deveined, 31–40 count)
- Baby spinach (16 oz, two big handfuls at a time)
- Unsalted butter (3 tbsp)
- Olive oil (1 tbsp)
- Garlic (6 cloves, minced)
- Lemon (1 large, zested and juiced)
- Crushed red pepper flakes (1/2 tsp, adjust to heat tolerance)
- Smoked paprika (1 tsp)
- Sea salt (1–1.5 tsp, divided)
- Black pepper (3/4 tsp)
- Fresh parsley (1/4 cup, chopped)
- Optional add-ons (still under 400 calories if portioned smart):
- Cherry tomatoes (1 cup, halved)
- Lemon wedges for serving
- Cooked cauliflower rice or zucchini noodles (for extra volume)
- Grated Parmesan (1–2 tsp per serving)
The Method – Instructions
- Pat the shrimp dry. Moisture is the enemy of good sear. Toss with 1/2 tsp salt, black pepper, smoked paprika, and half the lemon zest. Set aside.
- Heat the pan. Large skillet, medium-high heat.
Add olive oil and 1 tbsp butter. When it’s hot and foamy, you’re ready.
- Sear the shrimp. Add half the shrimp in a single layer. Cook 1–2 minutes per side until just pink and curled.
Don’t overcook. Remove to a plate and repeat with remaining shrimp.
- Build the garlic butter. Lower heat to medium. Add remaining 2 tbsp butter and the minced garlic.
Stir 30–45 seconds until fragrant (not brown). Add red pepper flakes and the rest of the lemon zest.
- Wilt the spinach. Add spinach in batches with a pinch of salt. Toss until just wilted—about 2–3 minutes total.
If using cherry tomatoes, toss them in now for 1 minute to soften slightly.
- Finish with brightness. Return shrimp to pan. Add lemon juice and parsley. Toss to coat.
Taste and adjust salt/pepper. You want zippy, garlicky, buttery balance.
- Assemble the meal prep. Divide evenly into 4–5 containers. For extra volume, add 1/2 cup cooked cauliflower rice or zoodles per container.
Optional: sprinkle 1–2 tsp Parmesan.
- Cool before sealing. Let containers stand 10–15 minutes so condensation doesn’t sog out the spinach. Then seal.
Macros (approx per serving, 5 servings without add-ons): 250–320 calories, 30–35g protein, 12–16g fat, 5–7g carbs. With 1/2 cup cauliflower rice: +15–20 calories.
With 2 tsp Parmesan: +20 calories. Still under 400—comfortably.
Storage Instructions
- Fridge: Store in airtight containers up to 3 days for best texture (4 max). Shrimp are delicate; fresher is better.
- Freezer: Not ideal due to spinach texture, but possible.
Freeze up to 1 month in freezer-safe containers. Thaw overnight in fridge.
- Reheating: Microwave 60–90 seconds until warm; don’t nuke it to death. Or skillet on low 2–3 minutes with a splash of water.
Add a squeeze of lemon after reheating to revive brightness.
Why This is Good for You
- High protein, low calories: Shrimp loads you up with protein without the calorie tax. That means satiety that fits your goals.
- Micronutrient-dense: Spinach brings iron, folate, vitamin K, and fiber. Garlic supports flavor and, IMO, happiness.
- Healthy fats, smart balance: Butter for richness, olive oil for heart-healthy fats, lemon to cut through and keep you craving it tomorrow.
- Low carb, flexible: Add cauliflower rice or zoodles for volume without breaking the calorie bank.
What Not to Do
- Don’t overcook shrimp. Rubbery shrimp are culinary heartbreak.
Pull them when they just turn pink and curl.
- Don’t drown it in butter. More butter doesn’t equal better if you care about calories. Measure it.
- Don’t skip the lemon. Acid balances the butter and garlic. Without it, the dish tastes flat.
- Don’t pack it steaming hot. You’ll trap moisture and get soggy spinach.
Cool briefly first.
- Don’t use wet spinach. If you washed it, spin or pat it dry. Excess water dilutes the sauce.
Alternatives
- Protein swaps: Use scallops, cubed firm tofu, or chicken breast strips. For tofu, press and sear until golden before adding garlic butter.
- Greens swaps: Try kale (pre-steam 2 minutes), Swiss chard, or arugula for a peppery kick.
Cooking time may vary slightly.
- Flavor twists: Add 1 tsp Dijon or 1 tbsp white wine to the pan after garlic for a pan sauce vibe. Or swap smoked paprika for Old Bay.
- Carb add-ons (still under 400): 1/3 cup cooked quinoa or 1/2 cup farro if you want more chew—just portion accordingly.
- Dairy-free: Replace butter with vegan butter or add 1 tbsp olive oil + splash of coconut milk for creaminess.
FAQ
How do I keep shrimp from getting rubbery when I reheat?
Reheat gently—short bursts in the microwave (30 seconds, stir, then 20–30 seconds more) or low heat in a skillet with a splash of water. Stop as soon as it’s warm.
Overheating is the enemy here.
Can I use frozen shrimp?
Absolutely. Thaw overnight in the fridge or under cold running water for 10–15 minutes. Pat very dry before seasoning so you get a better sear and avoid watery results.
Is this spicy?
Mildly.
The red pepper flakes add a whisper of heat, not a shout. Reduce or omit them if you’re heat-shy, or double if you like it feisty.
How can I make it more filling without adding many calories?
Add cauliflower rice, spiralized zucchini, or extra spinach. These bulk up volume and fiber with minimal calories, keeping each portion satisfying and still under 400.
What’s the best pan to use?
A large nonstick or seasoned stainless-steel skillet works well.
Crowding the pan steams the shrimp, so size matters. Cook in batches for better browning and flavor.
Can I meal prep this for the whole week?
Stick to 3–4 days max for best texture and safety. If you want a full week, prep a double batch and freeze half, or cook a second round midweek.
FYI: Shrimp quality drops after day three.
Can I reduce the butter more?
Yes. You can cut to 2 tbsp butter and add 1 tsp olive oil. The flavor will still be lush, especially with lemon and garlic doing the heavy lifting.
What if I don’t like parsley?
Use basil, dill, or chives.
Each brings a different vibe: dill is bright and briny, basil is sweet and aromatic, chives are subtle and oniony.
