Best Low Carb Meal Prep – Easy 30-Minute Dinners

We all know the struggle: it's 6 PM, you're tired, and the takeout menu is calling. That's why I started meal prepping – it's the only way I stick to my low-carb goals without losing my mind.

This Low Carb Meal Prep is my weeknight savior. It's a simple, balanced meal of seasoned chicken thighs, colorful roasted vegetables, and a velvety cauliflower mash that tastes indulgent but is secretly good for you.

Make it on Sunday, and you have four days of grab-and-go lunches or dinners. It's realistic, delicious, and keeps your energy steady all week.

About the Ingredients

1.5 lbs (680g) boneless, skinless chicken thighs

Thighs stay juicy and flavorful. You can use breasts, but reduce cooking time by 5 minutes to avoid dryness.

2 tbsp (30ml) olive oil, divided

Use extra-virgin for flavor. Avocado oil works too and has a higher smoke point.

1 tsp garlic powder

Fresh garlic is great, but powder distributes better on meal prep. Use 2 cloves minced if you prefer.

1 tsp smoked paprika

Adds a smoky depth. Sweet paprika works, but you'll miss the smokiness.

1/2 tsp salt

Kosher salt is best for even seasoning. Sea salt works too.

1/4 tsp black pepper

Freshly ground is more aromatic. Pre-ground works in a pinch.

1 medium head cauliflower (about 2 lbs / 900g), cut into florets

For the mash. You can buy pre-cut florets to save time.

2 tbsp (30g) cream cheese, softened

Adds creaminess. For dairy-free, use 2 tbsp coconut cream.

2 tbsp (30g) butter

Use grass-fed for better flavor. Substitute with ghee for dairy-free.

1 lb (450g) Brussels sprouts, halved

Roast them for a nutty taste. Broccoli florets are an easy swap.

1 red bell pepper, sliced

Adds sweetness and color. Any color pepper works.

1 red onion, cut into wedges

Roasts sweet and tender. Yellow onion is fine too.

Tips & Tricks

• Don't overcrowd the baking sheet – give veggies space to roast, not steam.
• Let the chicken rest before slicing to keep it juicy.
• Portion into containers while warm, then refrigerate – it helps the flavors meld.

Step-by-Step Instructions

1. Marinate the chicken

In a bowl, toss chicken thighs with 1 tbsp olive oil, garlic powder, paprika, salt, and pepper. Let sit while you prep veggies.

2. Preheat oven to 425°F (220°C)

Preheat to 425°F (220°C). This high heat gives the veggies caramelized edges and the chicken a nice crust.

3. Roast the vegetables

On a large baking sheet, toss Brussels sprouts, bell pepper, and onion with remaining 1 tbsp olive oil and a pinch of salt. Spread in a single layer. Roast for 20 minutes, until edges are golden brown and tender.

4. Cook the chicken

While veggies roast, heat a skillet over medium-high heat. Add chicken thighs and cook 5-6 minutes per side, until golden brown and internal temp reaches 165°F (74°C). Rest for 5 minutes.

5. Steam the cauliflower

Place cauliflower florets in a microwave-safe bowl with 2 tbsp water. Cover and microwave for 8-10 minutes, until fork-tender. (Or steam on stove.)

6. Make the mash

Drain cauliflower well. In a food processor, blend with cream cheese, butter, salt, and pepper until smooth and creamy. Adjust seasoning to taste.

7. Assemble containers

Divide chicken, veggies, and cauliflower mash evenly among 4-6 meal prep containers. Let cool slightly, then seal and refrigerate.

Delicious Variations

• Swap chicken for salmon – cook at 400°F (200°C) for 12-15 minutes until flaky.
• Add a sprinkle of red pepper flakes for heat.
• Use broccoli and zucchini instead of Brussels sprouts and bell pepper.
