Choosing the Right Vegetables for Roasted Vegan Tomato And Cauliflower Bisque
Best Vegetables for This Recipe
Roma tomatoes work exceptionally well because of their meaty texture and lower water content, which concentrates beautifully when roasted. Medium-sized cauliflower heads provide the perfect creamy base – look for tight, white florets without brown spots.
Buying Tips
Look for tomatoes that give slightly to gentle pressure but aren’t overly soft. The skin should be smooth and vibrant red. For cauliflower, choose heads with bright white florets and fresh green leaves. Avoid any with dark spots or yellowing.
Substitutions
Swap Roma tomatoes for cherry tomatoes (increase quantity by half) or use fire-roasted canned tomatoes in winter. Replace cauliflower with roasted butternut squash for a sweeter variation.
