Can I meal prep Keto Herb-Crusted Salmon with Roasted Cauliflower Mash?

Yes. Portion it into airtight containers and keep toppings, sauces, or crunchy finishes separate when that will protect the texture.

How can I increase the protein?

Add a little more salmon or pair the recipe with a compatible high-protein side such as Greek yogurt, eggs, tofu, beans, or lean meat depending on the recipe style.

Can I make it lighter?

Use measured oil, lighter dairy or sauce options, and a larger vegetable portion while keeping the main protein amount steady.

What should I watch when swapping ingredients?

Keep moisture, salt, and cooking time in mind because high-protein swaps can dry out or firm up faster than the original ingredient.

Instructions

Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper or foil.
In a small bowl, mix together rosemary, thyme, garlic powder, lemon zest, salt, and black pepper to create the herb crust.
Pat the salmon fillets dry with paper towels and brush both sides with 1 tablespoon of olive oil.
Press the prepared herb mixture firmly onto the top sides of the salmon fillets, forming an even crust.
Arrange salmon fillets skin-side down on the prepared baking sheet.
Toss cauliflower florets with the remaining 1 tablespoon olive oil, salt, and pepper; spread evenly on a separate baking sheet.
Roast the cauliflower for 20-25 minutes, turning once halfway, until golden and tender.
Place the salmon in the oven and bake for 12-15 minutes until cooked through and easily flaked with a fork.
While baking, melt butter in a small skillet over medium heat. Add minced garlic and sauté for 1 minute until fragrant.
Transfer roasted cauliflower to a food processor or blender. Add garlic butter and heavy cream, then blend until smooth and creamy. Season with salt and pepper to taste.
Serve each salmon fillet on a bed of roasted cauliflower mash, garnished with chopped parsley and lemon wedges on the side.

Tips

Protein Highlight

salmon gives this seafood recipe its main protein focus, while supporting ingredients add texture, fiber, or slow-burning carbohydrates. Keep the protein portion clear on the plate instead of letting sauces, toppings, or starches become the bulk of the meal.

Goal Fit

This recipe fits meal prep, active-week eating, and balanced family meals because it combines familiar ingredients with a fitness-friendly structure. Use it when you want a practical option that can support recovery, satiety, or steady energy without turning the meal into a supplement-style dish.

Protein Density

To keep the protein density strong, measure calorie-dense extras and add more salmon or a compatible high-protein side before increasing the starch or sauce. If you scale the recipe, preserve the ratio between the protein base and the vegetables, grains, or toppings.
