Ingredients
For the Main Dish:
- 2 tablespoons olive oil
- 1 medium onion, diced
- 3 cloves garlic, minced
- 1 (28-ounce) can crushed tomatoes
- 2 cups vegetable or chicken broth
- 1 cup whole milk or half-and-half
- 1/2 teaspoon salt (adjust to taste)
- 1/4 teaspoon black pepper
- 1/2 teaspoon sugar (optional, balances acidity)
- 1/4 teaspoon red pepper flakes (optional, for a gentle kick)
- 1/2 cup fresh basil leaves, chopped
- 1 1/2 cups shredded sharp cheddar cheese
- 1/2 cup shredded mozzarella cheese
How I Make It
Step 1:
Heat the olive oil in a large pot over medium heat. Toss in the diced onion and let it soften for about 5 minutes, stirring occasionally. You’ll know it’s ready when the onions turn translucent and smell sweet — like a fresh bakery. Add the minced garlic and cook for another 30 seconds, just until it’s fragrant. Be careful not to burn it; burnt garlic is the enemy here!
Step 2:
Pour in the crushed tomatoes and broth. Stir everything together and bring to a gentle simmer. I like to add the salt, black pepper, and a pinch of sugar now. This little touch cuts the acidity of the tomatoes without making it taste sweet. If you want a bit of heat, sprinkle in the red pepper flakes. Let it bubble away for around 10 minutes — this lets the flavors mingle and deepen beautifully.
Step 3:
Turn the heat to low and pour in the milk or half-and-half, stirring gently. Watch as the soup turns creamy and takes on a gorgeous rosy hue. Toss in most of the basil (save some for garnish) and stir— your kitchen will smell like summer in Italy! Use an immersion blender right in the pot to blend the soup until nicely smooth but with just a touch of texture. No immersion blender? No worries, a regular blender works—just blend in batches and be sure to vent the lid slightly to avoid pressure build-up.
Step 4:
Sprinkle in the shredded cheddar and mozzarella cheeses. Stir until the cheeses melt completely, creating that luscious, stretchy texture we all crave. Taste and adjust seasoning here—maybe a little extra salt or pepper. When the cheese has melted and the soup is steaming hot, you’re golden.
Step 5:
Ladle the soup into bowls and sprinkle with the reserved fresh basil. If you want to get fancy, add a swirl of cream or a pinch of extra cheese on top. Serve right away with crusty bread or grilled cheese on the side. Oh, the crunch paired with creamy tomato? Pure magic.
Pro Tips
- If your broth is super salty, cut back on adding more salt until the end; it’s easier to add than fix.
- To avoid a grainy cheese texture, shred your own cheese instead of buying pre-shredded — it melts so much better!
- Simmering the soup gently instead of boiling keeps flavors fresh and cheese silky.
- Don’t skip fresh basil — dried just won’t deliver that vibrant, herbal punch!
Common Mistakes to Avoid
- Skipping preheating: A cold pan makes onions sweat instead of saute and can turn the soup bitter.
- Overmixing: Blending too long can make the soup gluey. Aim for smooth but still a little rustic.
- Guessing cook time: Use a timer for simmering — flavor development is all about that gentle cook.
- Overcrowding pans: Resist the urge to dump everything in at once! Cook onions in batches if needed for best flavor.
Alternatives & Substitutions
- Substitute vegetable broth for chicken to keep it vegetarian.
- Swap cheddar for pepper jack if you want a little spice.
- Use coconut milk instead of dairy for a creamy, dairy-free twist (taste will be a bit sweeter).
- Fresh spinach or kale can be stirred in at the end for a green boost and texture contrast.
Variations & Tips
- Make it spicy by adding a dash of smoked paprika or cayenne pepper.
- For a kid-friendly version, leave out red pepper flakes and use mild cheese.
- Top with homemade croutons or toasted pine nuts for crunch.
- Add a splash of balsamic vinegar to brighten the tomato base right before serving.
- Try swapping the basil for fresh thyme or oregano for an herb twist.
- For an indulgent twist, swirl in a spoonful of pesto just before serving.
FAQ (Frequently Asked Questions)
- Can I make this ahead of time?
- Yes! Make the soup up to 3 days ahead and store it in an airtight container in the fridge. Reheat gently on the stove to prevent curdling the cheese.
- Can I double the recipe?
- Absolutely. Just use a bigger pot and watch the simmer time — it might take a bit longer to heat through evenly.
- Can I substitute butter with oil?
- Since this recipe uses olive oil, it’s already butter-free, but if you want a buttery flavor, just toss in a tablespoon of butter with the onions.
- How do I know it’s done?
- When the onions are soft and sweet, the tomatoes have simmered and thickened slightly, and the cheese melts smoothly into the soup without clumping.
- What if I don’t have fresh basil?
- Frozen basil works in a pinch, but add it towards the end so it doesn’t get bitter. Alternatively, stir in dried basil with the tomatoes, but use half the amount.
How I Like to Serve It
I love serving this soup on a chilly weeknight alongside a grilled cheese sandwich with extra melty cheese (hello, comfort overload!). It’s a fantastic option for casual family dinners, and leftovers heat up beautifully for lunch the next day. For a lighter take, a simple side salad dressed with lemon vinaigrette pairs nicely. Oh, and don’t forget crusty bread to soak up every last drop of that luscious, cheesy tomato goodness — trust me, it’s worth it.
Notes
- This soup keeps well in the fridge for up to 3 days — just reheat gently to keep it silky.
- If reheating in the microwave, stop and stir every minute to prevent hotspots and curdling.
