Pat brussels sprouts completely dry with paper towels after washing to ensure maximum crispiness on the outside when smashing and cooking in olive oil.

Wait until brussels sprouts are fork-tender (about 20-25 minutes roasting) before smashing to achieve that ideal creamy interior without over-mashing into a mushy texture.

Add half the vegan cheese before the final roast and the remaining half immediately after smashing while still hot, ensuring even melting and maximum flavor distribution.

Toast garlic and herbs in your olive oil for 1-2 minutes before tossing with brussels sprouts to create a more complex, restaurant-quality flavor foundation.

Season brussels sprouts before roasting, taste after smashing, and finish with fleur de sel for brightness—this multi-stage approach prevents under-seasoning and enhances depth.
