How to Make Roasted Cauliflower Soup
Step 1: Get Ready
Preheat your oven to 425°F. Cut the cauliflower in half from top to bottom through the stem. Use your knife to slice off each floret carefully. If some florets are larger than others, slice them into smaller pieces so they cook evenly.
Step 2: Season the Cauliflower
Transfer your chopped cauliflower onto a large sheet pan. Sprinkle generously with kosher salt and black pepper before drizzling with extra virgin olive oil. Toss everything together until well coated. Spread them out evenly without overlapping—this helps achieve that perfect roasted flavor.
Step 3: Roast the Cauliflower
Place your seasoned cauliflower in the oven and roast for about 45 minutes. Give them a turn halfway through to ensure even browning. You want them tender and deeply browned in some spots—this enhances their natural sweetness.
Step 4: Sauté the Onions
In a large heavy pot or Dutch oven, heat two tablespoons of olive oil over medium heat until shimmering but not smoking. Add your chopped onions and cook until they’re translucent—about seven minutes. This step brings out their sweetness! Next, add garlic along with cumin, paprika, sumac, and turmeric. Stir until fragrant for about one minute.
Step 5: Simmer
Now it’s time to add three-quarters of your roasted cauliflower (saving some for garnish). Stir well to coat everything with those aromatic spices before adding your vegetable broth and one cup of water. Bring this mixture to a boil over high heat then lower it back down to medium, covering part-way. Let it simmer until slightly thickened—this should take about five to seven minutes.
Step 6: Blend
Uncover your pot and remove it from heat momentarily. Using an immersion blender, blend everything together until you reach your desired smoothness—I personally like mine just on the chunky side! If using a traditional blender or food processor, remember to leave room at the top and blend safely.
Step 7: Finish and Serve
Return your blended soup back onto medium heat. Stir in whole milk or plant-based milk along with lemon juice and reserved cauliflower pieces. Allow everything to warm through nicely before tasting and adjusting salt if needed. Finally, stir in fresh dill right before serving hot!
This Roasted Cauliflower Soup is not only comforting but also nutritious—a true delight for any occasion! Enjoy every spoonful!
Pro Tips for Making Roasted Cauliflower Soup
Making the perfect roasted cauliflower soup is simple with a few handy tips. Here are some insights to elevate your cooking experience!
-
Choose Fresh Cauliflower: Fresh cauliflower will yield the best flavor and texture. Look for heads that are firm, with tightly packed florets and vibrant green leaves.
-
Don’t Skip the Roasting: Roasting the cauliflower brings out its natural sweetness and adds depth of flavor. Make sure to give it enough time in the oven to develop those beautiful caramelized edges.
-
Customize Your Spices: Feel free to adjust the spices based on your taste preferences! If you like more heat, add some cayenne pepper or chili flakes. For a different flavor profile, try adding curry powder.
-
Blend Until Smooth: Using an immersion blender allows you to control the consistency of the soup. If you prefer a chunkier texture, blend just until combined; for a silky finish, blend until completely smooth.
-
Adjust Consistency with Broth or Milk: If you find your soup is too thick after blending, simply stir in more vegetable broth or milk until it reaches your desired consistency.
