This cozy bowl of alphabet soup brings back every warm memory of childhood, but better. Tender roasted vegetables blend into a rich, savory broth that tastes like comfort in a bowl, with little pasta letters floating through each spoonful. I first made this version on a rainy Tuesday when William asked if we could “make the soup with the ABCs,” and I realized we could create something healthier than the canned stuff without losing any of that nostalgic magic. The roasted vegetables give this plant-based soup incredible depth, and it comes together easily with simple ingredients you probably already have.
If you’re looking for more wholesome dinner recipes, this one’s a keeper, and it pairs beautifully with dishes like this Best Zucchini Risotto Recipe or these Healthy Eggplant Mozzarella Sandwiches or This Delicious Sheet Pan Crunchwrap Recipe.

Ingredients For Alphabet Soup
Everything you need is simple and wholesome.
See Recipe Card Below This Post For Ingredient Quantities
Vine-ripe tomatoes: These roast down into a sweet, concentrated base that gives the soup its rich tomato flavor. Fresh tomatoes work much better than canned for roasting.
Red bell pepper: Adds natural sweetness and a beautiful color to the broth. Roasting brings out the pepper’s sugars and creates depth.
Onion: Provides a savory backbone and helps balance the sweetness from the tomatoes and pepper. Any yellow or white onion works perfectly.
Zucchini: Adds body and a mild vegetable flavor without overpowering the soup. It blends smoothly and makes the texture silky.
Carrot: Brings a touch of natural sweetness and boosts the nutrition. Roasted carrots develop a lovely caramelized flavor.
Garlic: Roasted garlic becomes mellow, sweet, and nutty. It adds layers of flavor without the sharpness of raw garlic.
Avocado oil: Helps the vegetables roast evenly and develop those caramelized edges. You can swap it for olive oil if that’s what you have on hand.
Salt and black pepper: Essential for bringing out all the flavors. Season generously before roasting and adjust again at the end.
Vegetable broth: Forms the liquid base of the soup. Use a good-quality store-bought version or make your own for the best flavor.
Alphabet pasta: The star of the show! These little letters make the soup fun and nostalgic. Look for whole wheat or gluten-free versions if you prefer.
Italian seasoning: A blend of herbs like basil, oregano, and thyme that gives the soup a classic Italian-inspired warmth.
Nutritional yeast: Adds a subtle cheesy, umami flavor that makes the broth taste richer and more complex. It’s a plant-based pantry staple.
How to Make Alphabet Soup
Here’s everything you need to know to make this comforting kids alphabet soup from scratch.
Preheat oven: Set your oven to 400°F (200°C) and line a large baking sheet with parchment paper or a reusable silicone mat. This prevents the vegetables from sticking and makes cleanup easier.
Prepare the vegetables: Spread the tomatoes, bell pepper, onion, zucchini, carrot, and garlic cloves across the baking sheet. Drizzle with avocado oil and season generously with salt and pepper, tossing everything to coat evenly.
Roast the vegetables: Slide the pan into the oven and roast for 35 minutes, or until the vegetables are soft, slightly charred at the edges, and fragrant. The tomatoes should look collapsed and jammy.
Cook the broth: While the vegetables roast, pour the vegetable broth into a soup pot and bring it to a gentle boil over medium-high heat. In a separate pot, cook the alphabet pasta according to package directions until al dente, then drain and set aside.
Blend the vegetables: Once the roasted vegetables have cooled slightly and are safe to handle, transfer them carefully to a high-speed blender. Puree on high until completely smooth and creamy, scraping down the sides if needed.
Combine soup base: Pour the silky vegetable puree into the pot of hot broth, stirring well to combine. The soup should turn a gorgeous orange color and smell incredible.
Season and serve: Stir in the Italian seasoning, nutritional yeast, and additional salt and pepper to taste. Add the cooked alphabet pasta, mix everything together, and ladle into warm bowls. Serve hot with crusty bread if you like.
Kitchen Notes & Swaps
You can customize this roasted Alphabet Soup with pasta to fit what you have at home.
Substitute pasta shapes: If you don’t have alphabet pasta, orzo, small stars (pastina), or even ditalini work beautifully. The shape doesn’t change the flavor, just the fun factor.
Oil options: Olive oil works just as well as avocado oil for roasting. Both have high smoke points and add good flavor.
Spice it up: Add a pinch of red chili flakes or a dash of smoked paprika when you season the soup for a gentle kick and deeper flavor.
Gluten-free version: The soup base is naturally gluten-free. Just use gluten-free alphabet pasta or any gluten-free small pasta shape you can find.
Extra veggies: Toss in some roasted mushrooms, cherry tomatoes, or even a handful of spinach at the end for extra nutrition.
Equipment For Alphabet Soup
You don’t need anything fancy to make this easy alphabet soup for kids.
A sturdy baking sheet helps the vegetables roast evenly. Line it with parchment paper or a silicone mat to prevent sticking and make cleanup quick.
A high-speed blender is key for getting that smooth, creamy texture. An immersion blender works too if you prefer to blend directly in the pot.
Use one soup pot for heating the broth and another pasta pot for cooking the alphabet noodles separately. This keeps the soup from getting too starchy.
Storage & Reheating
This comfort food alphabet soup stores beautifully and tastes even better the next day.
Let the soup cool to room temperature, then transfer it to an airtight container. Store in the refrigerator for up to 5 days. The pasta will absorb some of the broth as it sits, so you might want to add a splash of vegetable broth when reheating.
To reheat, warm gently on the stovetop over medium-low heat, stirring occasionally. You can also microwave individual portions in 1-minute intervals, stirring between each round.
For longer storage, freeze the soup base without the pasta. Cook and add fresh pasta when you’re ready to serve. The soup freezes well for up to 3 months in a freezer-safe container.
Serving Ideas
This healthy tomato-based soup pairs perfectly with simple, cozy sides.
Serve it with warm, crusty sourdough bread for dipping. The tangy bread complements the sweet roasted vegetables beautifully.
A simple green salad with lemon vinaigrette makes a light, fresh contrast to the warm soup. Toss in some cherry tomatoes and cucumbers for extra crunch.
For a heartier meal, pair it with a grilled cheese sandwich made with plant-based cheese. Kids especially love this combination.
Top each bowl with a sprinkle of fresh basil or parsley and a drizzle of good olive oil for an elegant finishing touch.
Expert Tips
These little tricks make your homemade alphabet pasta soup even better.
Don’t skip the roasting step. Roasting the vegetables instead of sautéing them creates deeper, sweeter flavors that make this soup taste restaurant-quality.
Cook the pasta separately. This keeps the soup from getting cloudy and starchy. It also makes storage easier since you can freeze the base without pasta.
Adjust the consistency. If your soup is too thick after blending, thin it with more vegetable broth. If it’s too thin, let it simmer for a few extra minutes to reduce.
Taste and season at the end. The nutritional yeast and Italian seasoning add a lot of flavor, so always taste before adding more salt.
Add pasta right before serving. If you’re meal prepping, store the pasta separately and add it to each bowl as you heat portions. This keeps the letters from getting mushy.
FAQ
Did Campbell’s discontinue alphabet soup?
Campbell’s still makes alphabet soup, but it’s widely available in stores and online. However, making your own version at home lets you control the ingredients and skip the preservatives. This homemade vegetable soup with pasta tastes fresher and has way more vegetables than the canned kind. Plus, you can customize the flavor however you like.
What does alphabet soup slang mean?
In slang, “alphabet soup” refers to something that uses a lot of acronyms or abbreviations, like government agencies (FBI, CIA, NASA). It’s called that because mixing all those letters together looks like alphabet soup! The term comes from the classic soup itself, where letters float around in the broth.
What are the ingredients of ABC soup?
Traditional ABC Soup (or alphabet soup) usually includes a tomato-based broth, vegetables like carrots and celery, and alphabet-shaped pasta. This healthier version uses roasted tomatoes, bell pepper, zucchini, onion, carrot, and garlic for a richer base, plus vegetable broth and nutritional yeast for extra flavor. The alphabet pasta makes it fun and nostalgic. You can find similar wholesome ideas in other dinner recipes on the site.
How are the letters in alphabet soup made?
Alphabet pasta is made from simple pasta dough (usually flour and water or flour and eggs) that’s pressed through special letter-shaped molds or dies during the extrusion process. The dough gets pushed through these tiny letter shapes, cut, and then dried. It’s the same process used for other pasta shapes, just with alphabet molds instead. Most brands use fortified wheat flour for added nutrition.
