Step 1: Roast the Vegetables

Begin by preheating your oven and tossing the broccoli florets, sliced yellow onion wedges, and whole head of garlic with olive oil, dry mustard powder, nutritional yeast, kosher salt, black pepper, and a pinch of cayenne for that subtle heat. Spread everything out evenly on a sheet pan—this is the magic part where the roasting concentrates the flavors, caramelizing the edges and transforming the garlic into a golden, spreadable treasure.

Step 2: Prepare the Broth Base

While the veggies roast to a tender crisp, pour the chicken broth into a large pot on the stove and bring it to a gentle simmer. Once the veggies are done roasting and slightly cooled, squeeze the softened garlic cloves out of their skins and add them along with the broccoli and onion to the broth. Then, toss in the packed baby spinach, allowing it to wilt and brighten the soup with fresh color and flavor.

Step 3: Blend for Creaminess

Using an immersion blender, pulse the soup right in the pot until it reaches your preferred consistency—somewhere between smooth and a little chunky is perfect. This creamy blend showcases those roasted veggies beautifully while keeping a rustic feel.

Step 4: Add the Cheesy Goodness

Lower the heat to a gentle warmth and incorporate the shredded sharp cheddar and parmesan cheeses, stirring until melted and silky. The cheeses bring richness and that irresistible gooey texture that makes this sheet pan broccoli cheddar soup recipe stand out.

Step 5: Make Grilled Cheese Croutons

Butter your slices of sourdough bread and layer cheddar slices between them. Grill them in a pan until golden and crispy on the outside, gooey on the inside. Then, cut into bite-sized croutons ready to float atop—or dunk into—your luscious soup.

How to Serve Sheet Pan Broccoli Cheddar Soup Recipe

Garnishes

Bring your soup to life by sprinkling freshly grated parmesan cheese over the top along with a few grilled cheese croutons. If you want a bit more texture and color, a few additional baby spinach leaves or a swirl of extra virgin olive oil can make it look and taste even more inviting.

Side Dishes

This soup pairs perfectly with a crisp green salad or roasted root vegetables to keep the meal balanced. If you’re going all in on carbs, a warm baguette or garlic knots are incredible for scooping and soaking up every last bit.

Creative Ways to Present

For a fun twist, serve the soup in hollowed-out bread bowls and top with grilled cheese croutons like little edible jewels. Another idea is to marinate the soup with fresh herbs like thyme or chives for a fragrant touch that will wow guests.

Make Ahead and Storage

Storing Leftovers

Store your leftover broccoli cheddar soup in an airtight container in the refrigerator for up to 3 to 4 days. Keep the grilled cheese croutons separate to avoid sogginess—they’re best when crisp.

Freezing

You can freeze this soup in well-sealed freezer containers for up to 2 months. Because of the cheese content, it’s best to avoid freezing the grilled cheese croutons, but the soup itself re-heats beautifully and still tastes fresh.

Reheating

When reheating, warm the soup gently on the stove over low to medium heat, stirring occasionally. If the soup thickens too much, just add a splash of broth or water to restore the perfect comforting texture. Reheat your croutons separately in the oven or toaster oven to regain their crispness.

FAQs

Can I make this soup vegetarian?

Absolutely! Just swap out chicken broth for a good-quality vegetable broth, and you’ll still get plenty of flavor and richness. Nutritional yeast also helps boost umami to keep everything satisfying.

What if I don’t have nutritional yeast?

If you don’t have nutritional yeast on hand, you can leave it out. It’s an extra depth element but the soup will still be wonderfully flavorful thanks to the roasted veggies and cheeses.

Can I use frozen broccoli florets?

Frozen broccoli can work in a pinch, but fresh broccoli offers the best texture and flavor, especially when roasted on the sheet pan. If using frozen, pat them dry to avoid excess moisture.

Is this soup gluten-free?

The soup itself is naturally gluten-free, but be sure to use gluten-free bread if you want the grilled cheese croutons to be safe for gluten-sensitive guests.

How can I make this soup creamier?

If you prefer your broccoli cheddar soup extra creamy, add a splash of cream or half-and-half at the end of cooking. You can also blend in some cooked potatoes or cauliflower along with the broccoli for added creaminess.
