How to Make Salmon with Creamy Avocado Sauce
Follow these straightforward steps for a flawless dinner:
Roasting the Cauliflower
Preheat your oven to 425°F (220°C). Start by slicing cauliflower into 3/4-inch (2 cm) thick steaks. Then gently coat both sides with olive oil and salt. Next mix harissa paste with additional oil, spreading this mixture generously over the cauliflower slices.
Arrange cauliflower on a baking sheet and roast for 20 minutes. After the first 20 minutes, carefully flip each piece. Continue cooking until golden and slightly charred, about 15 additional minutes.
Preparing the Avocado Sauce
While cauliflower roasts, combine avocado, basil, garlic, lemon juice, olive oil, cream, and salt in a blender. Blend until completely smooth—this typically takes 45-60 seconds. If needed, add extra lemon juice or water to thin the sauce to a pourable consistency.
Searing the Salmon
Pat salmon dry and season both sides with salt. Furthermore, heat butter or oil in a skillet over medium-high. Once hot, add salmon and cook for 3-4 minutes per side until nicely browned. Ultimately, cook time depends on thickness and preferred doneness.
Pro Tips for Success
These expert suggestions ensure your dish shines:
- Blend the avocado sauce early to allow flavors to meld
- Preheat pans thoroughly before adding salmon
- Use an instant-read thermometer for perfect doneness (120°F for medium-rare)
Presentation Secrets
For special occasions, garnish with edible flowers or microgreens. If serving family-style, consider some circus animal cookie dream bars for dessert to extend the joyful presentation theme.
Flavor Variations
You can customize this recipe in delightful ways:
Sauce Variations
- Cilantro-lime: Substitute cilantro for basil
- Spicy kick: Add jalapeño to the blender
- Herb garden: Mix parsley, dill, and chives

Serving Suggestions

Storage and Freezing Instructions
Store leftovers in airtight containers for up to 3 days. To rehe steak the sauce separately—microwave cauliflower and salmon gently covered with damp paper towel. However, the avocado sauce doesn’t freeze well due to texture changes.
For meal prep, you can roast cauliflower up to two days ahead. Shape leftover salmon into butterfinger ball-sized patties for quick salmon cakes later in the week.

FAQs About Salmon with Creamy Avocado Sauce
Can I use frozen salmon?
Yes, thaw frozen salmon completely before cooking, patting it dry to ensure proper searing. Frozen fillets may release more moisture, so increase heat slightly.
How do I prevent the avocado sauce from browning?
Press plastic wrap directly onto the sauce surface to limit air exposure. Acid from lemon juice also slows browning, but plan to use it within 6 hours.
What if my harissa paste is too spicy?
Temper the heat by mixing harissa with honey or maple syrup before coating cauliflower. Alternatively, use roasted red pepper paste.
Can I grill instead of pan-sear?
Absolutely—grill salmon over medium-high heat, oiling grates well. Watch for flare-ups especially with thicker fillets.
Is there a substitute for harissa?
Use smoked paprika mixed with chili powder and cumin as an alternative spice blend. Adjust ratios to match your preferred heat level.
