Classic Garlic Cheddar Soup

Cold weather always makes me crave soup. There’s something about a steaming bowl that just hits the spot when it’s chilly outside. But I’ll be honest – I used to think making soup from scratch was too much work for a busy weeknight.

That’s why this garlic cheddar soup changed everything for me. It comes together in about 30 minutes with ingredients I already have in my kitchen. No fancy stock-making or hours of simmering required. Just real comfort food that tastes like it took all day.

The best part? My kids actually ask for seconds. And when you’re dealing with picky eaters, that’s basically a miracle. I make a big batch on Sunday and we eat it throughout the week with crusty bread or grilled cheese sandwiches.

What Kind of Cheddar Cheese Should I Use?

For this soup, you’ll want to use sharp white cheddar cheese, and I highly recommend shredding it yourself from a block rather than buying pre-shredded. Pre-shredded cheese has anti-caking agents that can make your soup grainy instead of smooth and creamy. Sharp cheddar gives you that bold, tangy flavor that really makes this soup shine, but if you prefer a milder taste, medium cheddar will work too. When you’re shredding the cheese, make sure it’s cold from the fridge – it’s much easier to work with and won’t clump together as much.

Options for Substitutions

This creamy soup is pretty forgiving when it comes to swaps – here are some easy substitutions:

• Leek: If you can’t find leeks, use 1 medium yellow onion instead. It’ll give you that same mild onion flavor without the fuss of hunting down leeks.
• Parsnip: No parsnips? Try using an extra carrot or some chopped turnip. You could even add diced potato for a heartier texture.
• White wine: Skip the wine if you prefer – just use an extra 2/3 cup of chicken broth. If you want that slight tang, add a splash of white wine vinegar to the broth.
• Sharp white cheddar: Any good melting cheese works here. Try sharp yellow cheddar, gruyere, or even a mix of cheddar and cream cheese for extra richness.
• Evaporated milk: Heavy cream or half-and-half make great substitutes. Use the same amount, but add it at the very end and don’t let it boil to prevent curdling.
• Cornstarch: For thickening, you can use 4 tablespoons of flour mixed with cold water instead of cornstarch. Just whisk it in well to avoid lumps.

Watch Out for These Mistakes While Cooking

The biggest mistake when making garlic cheddar soup is adding the cheese too quickly or over high heat, which causes it to clump and become grainy instead of melting smoothly – always reduce the heat to low and add the cheese gradually while stirring constantly.

Another common error is not properly dissolving the cornstarch in cold water before adding it to the soup, which can create lumps that are hard to remove once they form.

Don’t rush the vegetable cooking process at the beginning – take time to properly soften the leeks, carrots, celery, and parsnips until they’re tender, as this builds the flavor foundation for your soup.

Finally, avoid boiling the soup once you’ve added the evaporated milk and cheese, as high heat can cause the dairy to curdle and ruin the creamy texture you’re working toward.

What to Serve With Garlic Cheddar Soup?

This rich and creamy soup is perfect with some crusty bread or warm dinner rolls for dipping and soaking up all that cheesy goodness. Since the soup already has such bold garlic and cheddar flavors, I like to keep sides simple – a fresh mixed greens salad with a light vinaigrette helps cut through the richness. You could also serve it alongside a grilled ham and cheese sandwich for the ultimate comfort meal, or try it with some crispy bacon bits sprinkled on top. For a lighter option, roasted vegetables like broccoli or Brussels sprouts make a nice contrast to the creamy soup.

Storage Instructions

Refrigerate: This garlic cheddar soup keeps really well in the fridge for up to 4 days in an airtight container. I actually think it tastes even better the next day because all those garlic and cheese flavors have more time to meld together. Just give it a good stir before serving since it might separate a little.

Freeze: You can freeze this soup for up to 3 months, but keep in mind that dairy-based soups sometimes get a bit grainy when thawed. I like to freeze it in individual portions using freezer bags laid flat – makes it so much easier to thaw just what you need for lunch or dinner.

Warm Up: Reheat your soup gently on the stovetop over medium-low heat, stirring frequently to prevent sticking. If it seems too thick after reheating, just whisk in a splash of chicken broth or milk. The microwave works too, but use 50% power and stir every minute to keep it from getting lumpy.

Ingredients

For the soup:

• 6 cloves garlic, finely minced (about 2 tbsp)
• 2 cans chicken broth (I use Swanson)
• 1/4 cup cold water
• 1 tbsp unsalted butter (I use Kerrygold for richness)
• 1/2 tsp ground black pepper (freshly ground preferred)
• 1/2 cup diced celery (about 1/4-inch pieces)
• 1 tbsp canola oil
• 1/2 cup diced carrots (about 1/4-inch pieces)
• 2 tbsp cornstarch (mixed with cold water to form slurry)
• 1 tsp salt
• 1 medium leek, white part only (sliced into thin rounds)
• 1 can evaporated milk (makes it extra creamy and rich)
• 2 cups grated sharp white cheddar cheese (room temperature for smooth melting)
• 1/2 cup diced parsnip (peeled, about 1/4-inch pieces)
• 2/3 cup dry white wine (or dry vermouth if preferred)

For garnish:

• Chopped fresh parsley (for color and freshness)
• Crushed baked pita chips (optional but adds nice crunch)

Step 1: Prepare Mise en Place and Build the Aromatic Base

• 1 tbsp unsalted butter
• 1 tbsp canola oil
• 1 medium leek, white part only
• 1/2 cup diced carrots
• 1/2 cup diced celery
• 1/2 cup diced parsnip
• 6 cloves garlic, finely minced

Slice the leek into thin rounds, dice the carrots, celery, and parsnip into uniform 1/4-inch pieces, and finely mince the garlic.

Having everything prepped and ready is essential for this soup since the vegetables will cook quickly once the butter and oil hit the pan.

Heat the butter and canola oil together in a large pot over medium heat until the butter is foaming and the mixture is shimmering.

This combination gives you the richness of butter with the higher smoke point of oil, preventing the butter from browning too quickly.

Step 2: Sauté Vegetables and Bloom the Garlic

• vegetables from Step 1
• 1 tsp salt
• 1/2 tsp ground black pepper

Add the leek, carrots, celery, and parsnip to the hot oil and butter, along with the salt and pepper.

Cook for 7-8 minutes, stirring occasionally, until the vegetables begin to soften and the leek becomes translucent at the edges.

The salt will help draw out moisture and begin the softening process.

Once the vegetables are starting to tender, add the minced garlic and cook for 1-2 minutes more, stirring constantly.

I like to cook the garlic for just a brief moment—enough to release its aromatic oils without letting it brown, which would make it taste bitter.

Step 3: Build the Broth and Simmer the Base

• sautéed vegetables from Step 2
• 2 cans chicken broth
• 2/3 cup dry white wine

Pour in the chicken broth and white wine, stirring to deglaze the bottom of the pot and incorporate any flavorful bits stuck to the pan.

Bring the mixture to a boil over medium-high heat, then reduce the heat to medium and simmer gently for 15-20 minutes.

This simmering time allows the vegetables to become completely tender and the flavors to meld together, creating a cohesive broth base.

Step 4: Blend and Thicken the Soup

• simmered broth from Step 3
• 2 tbsp cornstarch
• 1/4 cup cold water

Carefully blend the soup until completely smooth using an immersion blender, working in batches if needed.

Mix the cornstarch with the cold water to create a slurry, ensuring no lumps remain.

Pour the soup back into the pot (if you used a blender) and bring it to a simmer over medium heat.

Slowly stir in the cornstarch slurry while whisking constantly—the soup should begin to thicken noticeably.

Continue simmering for 2-3 minutes until the cornstarch is fully cooked and the soup reaches your desired thickness.

The soup should coat the back of a spoon but still pour easily.

Step 5: Enrich with Milk and Melt in the Cheese

• thickened soup from Step 4
• 1 can evaporated milk
• 2 cups grated sharp white cheddar cheese

Stir the evaporated milk into the thickened soup base, stirring well to combine.

The evaporated milk adds richness and body without making the soup too thin.

Remove the pot from high heat and reduce to low.

Add the room-temperature grated cheddar cheese in small handfuls, stirring constantly after each addition until completely melted before adding more.

Room-temperature cheese melts much more smoothly and evenly than cold cheese, preventing lumps or oiliness in the final soup.

Taste the soup and adjust seasoning with additional salt and pepper as needed.

Step 6: Serve and Garnish

• finished soup from Step 5
• crushed baked pita chips
• chopped fresh parsley

Ladle the soup into bowls and top each serving with crushed baked pita chips for a pleasant textural contrast and chopped fresh parsley for color and a fresh herbaceous note.

The warmth of the soup will slightly soften the pita chips while keeping them crispy enough to maintain that satisfying crunch.
