Step-by-Step Instructions

Preparing the Brussels Sprouts:
- Preheat your oven to 400°F (200°C).
- Toss the halved Brussels sprouts with olive oil, salt, and pepper in a bowl.
- Spread them on a baking sheet cut-side down and roast for 20-25 minutes until crispy and caramelized.
- While they’re roasting, mix balsamic vinegar with honey in a small saucepan and simmer for 3-4 minutes until slightly thickened.
- Drizzle the balsamic glaze over the Brussels sprouts once they’re done.
Making the Cauliflower Mash:
- Steam the cauliflower florets until very tender, about 8-10 minutes.
- Transfer the steamed cauliflower to a blender or food processor.
- Add chicken broth, butter, garlic powder, salt, and pepper.
- Blend until smooth and creamy, adding more broth if needed to reach your desired consistency.
- Keep warm until ready to serve.
Grilling the Shrimp:
- Pat the shrimp dry with paper towels and place them in a bowl.
- Add olive oil, minced garlic, paprika, salt, and pepper, and toss to coat evenly.
- Heat a grill pan or skillet over medium-high heat.
- Cook the shrimp for 2-3 minutes per side until pink and opaque.
- Squeeze fresh lemon juice over the shrimp just before removing from heat.
Plating:
- Spread the cauliflower mash on your plate as a base.
- Arrange the grilled shrimp on top of the mash.
- Place the roasted Brussels sprouts alongside the shrimp.
- Garnish with fresh herbs or an extra squeeze of lemon if desired.
Storage Instructions

Store each component separately in airtight containers in the refrigerator for up to 3 days. The shrimp stays freshest when stored alone and should be consumed within 2 days for best quality.
The cauliflower mash can be reheated in the microwave with a splash of chicken broth to restore its creamy texture. You can also reheat it on the stovetop over low heat, stirring frequently.
Brussels sprouts can be stored for up to 4 days and reheated in the oven at 350°F for 5-7 minutes to restore their crispiness. Avoid microwaving them as they’ll become soggy.
The balsamic glaze can be stored separately in a small jar for up to a week. Just give it a quick stir before using, as it may thicken when cold.
Why This Is Good for You
This meal delivers an impressive nutritional profile that supports your health goals. The 32 grams of protein from the shrimp helps maintain muscle mass and keeps you feeling satisfied for hours.
Cauliflower is incredibly nutrient-dense, providing vitamin C, vitamin K, and folate while being very low in calories. It’s also high in fiber, which aids digestion and helps regulate blood sugar levels.
Brussels sprouts are nutritional powerhouses packed with antioxidants, vitamins, and minerals. They’re particularly high in vitamin K and vitamin C, supporting bone health and immune function.
The low-fat nature of this meal makes it ideal for those on GLP-1 medications, as high-fat foods can sometimes exacerbate side effects like nausea. The fiber content helps with satiety and digestive health without causing discomfort.
Common Mistakes to Avoid
Don’t overcook the shrimp. They cook very quickly and become rubbery if left on heat too long. Remove them as soon as they turn pink and opaque.
Avoid adding too much liquid to the cauliflower mash at once. Start with less chicken broth and add more gradually until you reach the perfect creamy consistency.
Don’t skip patting the shrimp dry before seasoning. Excess moisture prevents proper browning and can make your shrimp steam rather than grill.
Make sure your Brussels sprouts are cut-side down on the baking sheet. This ensures they get that delicious caramelized crust that makes them so flavorful.
Don’t overcrowd the pan when cooking shrimp. Give them space so they sear properly rather than steam. Cook in batches if necessary.
Recipe Variations
- Spicy Version: Add red pepper flakes or cayenne to the shrimp marinade and drizzle the finished dish with sriracha or hot sauce.
- Herb-Crusted: Mix fresh herbs like parsley, dill, or cilantro into the cauliflower mash for added flavor and freshness.
- Lemon-Garlic: Double the garlic and add lemon zest to both the shrimp and cauliflower mash for a bright, zesty flavor profile.
- Asian-Inspired: Replace the balsamic glaze with a mixture of low-sodium soy sauce, rice vinegar, and a touch of sesame oil.
- Bacon Brussels: Add a tablespoon of crumbled turkey bacon to the Brussels sprouts for a smoky flavor without too much added fat.
Frequently Asked Questions
Can I use frozen shrimp for this recipe?
Absolutely! Just make sure to thaw the shrimp completely and pat them very dry before cooking. Frozen shrimp works just as well as fresh and is often more affordable.
What if I don’t have a grill pan?
A regular skillet works perfectly fine. You can also broil the shrimp in the oven for 2-3 minutes per side or use an outdoor grill if you have one.
Can I make the cauliflower mash ahead of time?
Yes, you can make it up to 2 days in advance. Store it in the refrigerator and reheat gently with a bit of extra chicken broth to restore the creamy texture.
How do I know when the shrimp are done?
Shrimp are fully cooked when they turn pink and opaque throughout. They should form a loose “C” shape. If they curl into a tight “O,” they’re overcooked.
Can I substitute the chicken broth with something else?
You can use vegetable broth, unsweetened almond milk, or even water. Chicken broth just adds the most flavor, but the mash will still be creamy with other liquids.
Is this recipe suitable for meal prep?
It’s great for meal prep! Just store the components separately and assemble when ready to eat. The shrimp is best consumed within 2 days, but the vegetables last longer.
