Ingredients for baked ziti soup

Pantry staples plus fresh herbs and a crispy celery crown—this one-pot wonder delivers creamy, comforting flavor in under 45 minutes.

The celery crown is the star—look for fresh, crisp stalks at the grocery store's produce section. Trader Joe's or Whole Foods have the best selection, but any well-stocked supermarket works. For the pasta, De Cecco or Barilla ziti holds up best during baking. The Parmesan makes all the difference—grate it yourself from a wedge, not pre-shredded. That creamy texture comes from warming the milk and cream together before adding to the sauce, so don't skip that step. The tomato sauce? Rao's or Muir Glen are my go-tos—they're consistent and flavorful without needing extra seasoning.

No fresh basil? Dried works at one-third the amount, but fresh has that bright, fresh flavor. Short on celery? Substitute with a ring of fennel or extra onion for the crown—just make sure it's sturdy enough to hold. Using low-sodium broth? Add an extra pinch of salt to compensate. The red pepper flakes are optional but add a nice kick—adjust to taste. For extra richness, stir in 2 tablespoons of cream cheese at the end. And if you're feeling fancy, top with a sprinkle of toasted pine nuts before serving.

This reheats beautifully—just cover with foil and warm in the oven for 10-15 minutes. Keeps 3-4 days in the fridge or 3 months frozen. I always make a double batch because it's that good. For the celery crown, trim the ends and slice into 1/4-inch thick rounds—they should fit snugly around the pot's edge. The dish tastes even better the next day as the flavors meld together. Store leftovers in an airtight container with a splash of broth to keep it moist.

Step-by-step instructions for baked ziti soup with crispy celery crowns

Here's how to create that dreamy combination of creamy pasta and crispy celery crowns in one pot!

Heat the 2 tablespoons olive oil in a large Dutch oven or deep oven-safe skillet over medium heat. Add the diced yellow onion and cook for 5 minutes until softened and translucent. You'll see the edges start to turn golden—that's your signal to add the 4 whole celery stems, cut into thick batons.

Cook the celery with the onion for another 3-4 minutes until it begins to soften slightly but still maintains some bite. This is crucial for those crispy crowns later. Add the 3 minced garlic cloves and cook for just 30 seconds until fragrant—don't let it brown or it'll turn bitter. This aromatic base forms the flavor foundation for your entire soup.

Pour in the 2 cups tomato sauce and 2 cups chicken broth, stirring to combine with the vegetables. Bring the mixture to a gentle simmer over medium-low heat, then reduce heat to maintain a bare simmer. Add the 1.5 teaspoons salt, 0.5 teaspoon black pepper, 1 tablespoon dried basil, 1 teaspoon dried oregano, and 0.5 teaspoon red pepper flakes if you want a little heat.

Simmer uncovered for 10 minutes to let the flavors meld together. You want the sauce to reduce slightly and develop depth—it should coat the back of a spoon but still be loose enough to coat the pasta later. Here's the thing—this simmering time is where all the magic happens. The acidity from the tomato sauce will brighten, and the spices will bloom beautifully.

Add the 8 ounces uncooked ziti pasta to the simmering sauce. Stir gently to distribute the pasta evenly. The pasta will start cooking immediately in the hot liquid. Cover the pot and simmer for 12-14 minutes, stirring occasionally, until the pasta is al dente—you should still have a slight bite to it when you taste it.

Don't walk away during this time. You want to check the pasta every few minutes to ensure it doesn't stick to the bottom. If it starts to stick, add a splash of water or broth to loosen it. The pasta should be tender but still hold its shape—it'll finish cooking in the oven later. This direct cooking method ensures maximum flavor absorption and that creamy texture we're after.

Once the pasta is al dente, remove the pot from heat and stir in the 0.5 cup warmed whole milk and 0.5 cup heavy cream. The cream will immediately start to thicken the sauce slightly—this is what gives our baked ziti its luxurious texture. Return the pot to low heat and let it warm through for just 2 minutes, stirring constantly to prevent curdling.

Here's where it gets fun—sprinkle half of the 0.5 cup grated Parmesan cheese over the top. The cheese will melt into the sauce, adding even more richness. Taste and adjust seasoning if needed. The soup should be perfectly balanced—savory from the tomato and meaty flavors, creamy from the dairy, and bright from the herbs and spices.

Preheat your oven to 375°F. Transfer the pot to the oven and bake uncovered for 15-20 minutes until the top is bubbly and the edges are golden brown. This baking step is what transforms our simple soup into something extraordinary—it develops that perfect texture where the top becomes slightly crispy while keeping the interior creamy and rich.

During the last 5 minutes of baking, watch closely. You want to see the celery stems standing up proudly from the surface, getting that beautiful golden brown color that signals crispiness. If the top starts to brown too quickly, tent it loosely with aluminum foil to prevent burning while still allowing it to bubble. The moment it reaches that perfect golden hue is when you know it's ready.

Flavor customization for this recipe

Creamy vs. Tomato-Dominant

Want to adjust the balance between creamy richness and tomato brightness? For a more tomato-forward flavor, reduce the cream to ¼ cup and add ½ cup extra tomato sauce—simmer it longer to deepen the flavor.

For extra creaminess, increase the heavy cream to ⅔ cup and stir in 2 oz cream cheese at the end for a velvety texture. 🍅

Spicy Heat Levels

Adjust the heat with red pepper flakes: start with ¼ tsp for mild warmth, ½ tsp for medium kick, or 1 tsp for fiery spice. For a smoky depth, swap the flakes for ½ tsp smoked paprika and add ½ tsp cayenne.

For a sweet-spicy twist, stir in 1 tsp honey with the red pepper flakes—it balances the heat beautifully. 🌶️

Vegetable Variations

Swap or add veggies to customize textures. Replace celery with 4 whole fennel stalks (trimmed) for a licorice note, or add 1 diced bell pepper for sweetness. For heartiness, stir in 1 cup diced mushrooms with the onions—they’ll absorb the sauce perfectly.

Roast 1 cup cherry tomatoes alongside the celery crown for a caramelized sweetness. 🥬

Protein Add-Ins

Boost protein by folding in 1 cup cooked chicken (shredded or diced) or ½ lb Italian sausage (browned and crumbled) during the final 5 minutes of baking. For seafood lovers, stir in 1 cup cooked shrimp just before serving—they’ll stay tender.

For a vegetarian twist, add 1 cup crumbled feta with the Parmesan for a tangy contrast. 🍗

Herb Swaps

Customize the herb profile: replace basil and oregano with 1 tbsp each of thyme and rosemary for a woodsy aroma, or add 1 tsp lemon zest for brightness. For a Mediterranean touch, swap in 1 tbsp dried marjoram and ½ tsp cinnamon (sounds odd, but it pairs surprisingly well!).

Fresh herbs like cilantro or parsley add a vibrant finish—garnish with 2 tbsp chopped fresh herbs before serving. 🌿

Dairy Adjustments

Make this dish dairy-free by replacing heavy cream with ½ cup coconut milk (full-fat for richness) and omitting the Parmesan—use nutritional yeast for a cheesy flavor. For lactose-free but still creamy, swap the heavy cream for ½ cup lactose-free cream cheese.

For a lighter option, reduce the cream to ¼ cup and add 1 tbsp cornstarch to thicken the sauce slightly. 🥛
