• 1/2 cup white onion, diced
• 1 teaspoon dried thyme
• 1 teaspoon dried oregano
• 1/2 teaspoon dried basil

How to Make Crockpot Tomato Soup

Step 1: Add ingredients to the slow cooker.

Add the crushed tomatoes, diced tomatoes, diced white onion, thyme, oregano, basil, sugar, salt, pepper, and bone broth to your crockpot. Stir everything together until combined.

Step 2: Add the butter.

Cut the butter into smaller pieces and add it to the slow cooker.

Step 3: Let it cook.

Cover and cook on LOW for 6–8 hours or HIGH for 3–4 hours, until the onions are softened and the flavors have blended together.

Step 4: Blend the soup.

Use an immersion blender to carefully blend the tomato soup until smooth and creamy. You can leave it slightly chunky if you prefer more texture.

Step 5: Make it creamy.

Stir in 1/2 cup of half & half, adding more as needed until you reach your desired consistency. Let everything warm through for another 5–10 minutes.

Taste and adjust the seasonings before serving!

How to Make Sheet Pan Grilled Cheese

Making grilled cheese in the oven is one of my favorite ways to prepare multiple sandwiches at once. You get crispy, buttery bread and perfectly melted cheese without having to make each sandwich individually.

Step 1: Preheat the oven.

Preheat your oven to 425°F.

Step 2: Assemble the sandwiches.

Butter one side of each bread slice. Place 4 slices of bread, buttered side down, on a large sheet pan.

Add 2 slices of cheese to each piece of bread, then top with the remaining bread slices, buttered side facing up.

Step 3: Bake.

Bake for approximately 6–8 minutes, then carefully flip each sandwich.

Step 4: Finish baking.

Return to the oven for another 4–6 minutes, or until the bread is golden brown and the cheese is completely melted. Keep an eye on the sandwiches, since oven temperatures and bread thickness can vary.

Step 5: Slice and serve.

Cut the sandwiches into halves or strips, and serve alongside your warm crockpot tomato soup for dipping!

Tips for Making the Best Homemade Tomato Soup

Blend for a smoother texture. If you love creamy tomato soup, an immersion blender makes it easy to get that smooth consistency right in your crockpot.

Adjust the creaminess. Start with 1/2 cup of half & half and add more if you want a richer, creamier soup.

Use your favorite bone broth. Chicken bone broth adds savory flavor, but vegetable broth works too if you’re looking for a vegetarian option.

Balance the acidity. Tomatoes can vary in acidity depending on the brand. The small amount of sugar helps balance the flavors, but you can always adjust it to taste.

Try different cheeses. Cheddar is delicious, but mozzarella, provolone, Monterey Jack, or a combination of cheeses would also work great for the sheet pan grilled cheese.

What to Serve with Tomato Soup and Grilled Cheese

While grilled cheese is the perfect pairing, there are plenty of other ways to enjoy this easy tomato soup!

Try serving it with a simple side salad, homemade croutons, garlic bread, or a sprinkle of freshly grated Parmesan cheese.

For an extra cozy meal, top the soup with fresh basil, cracked black pepper, and a little Parmesan.

How to Store and Reheat Leftovers

Refrigerator: Store leftover tomato soup in an airtight container in the refrigerator for up to 3–4 days.

Freezer: For the best texture, freeze the tomato soup before adding the half & half. Once cooled, transfer it to a freezer-safe container and freeze for up to 3 months.

Reheating: Reheat the soup over low heat on the stovetop or in the microwave, stirring occasionally. Add a splash of broth or half & half if needed.

Leftover grilled cheese sandwiches are best reheated in the oven or air fryer to help restore their crispy texture.

Frequently Asked Questions

Can I make tomato soup in the crockpot with canned tomatoes?

Absolutely! Canned crushed and diced tomatoes are perfect for slow cooker tomato soup. They make this recipe easy to prepare year-round without needing fresh tomatoes.

Do I have to blend the tomato soup?

No! If you enjoy a chunkier tomato soup, you can skip blending altogether. Blending creates a smoother, creamier texture, but it’s completely up to your preference.

Can I use heavy cream instead of half & half?

Yes! Heavy cream will make the soup a little richer and thicker. You can also use milk for a lighter version, although it won’t be quite as creamy.

Can you make grilled cheese in the oven?

Yes! Sheet pan grilled cheese is an easy way to make multiple sandwiches at once. Baking them in the oven creates a crispy exterior and melted cheese without needing to cook each sandwich separately.

Can I make this tomato soup dairy-free?

You can substitute the butter with a dairy-free alternative and use an unsweetened, plain dairy-free cream substitute in place of the half & half. The flavor and consistency may vary slightly.
