Ingredients for baked mac and cheese with tomatoes
These ingredients transform classic mac and cheese into a sun-dried tomato masterpiece—rich, tangy, and perfectly crisp on top.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 1 ½ lbs | Medium or short cut preferred |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, extra-sharp for best flavor |
| Heavy Cream 🥛 | 1 ½ cups | Full-fat for creamy texture |
| Whole Milk 🥛 | ½ cup | Warmed for smoother sauce |
| Sun-Dried Tomatoes 🍅 | ½ cup | Oil-packed, chopped fine |
| Butter 🧈 | ½ cup | Unsalted, melted |
| All-Purpose Flour 🌾 | 2 tbsp | For thickening the sauce |
| Garlic Cloves 🧄 | 4 cloves | Minced for aromatic depth |
| Yellow Onion 🧅 | 1 whole | Medium size, diced fine |
| Panko Breadcrumbs 🍞 | ½ cup | For crispy topping |
| Parmesan Cheese 🧀 | ¼ cup | Freshly grated for topping |
| Salt 🧂 | 1 ½ tsp | Kosher salt preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Dried Thyme 🌿 | ½ tsp | For subtle earthy flavor |
The sun-dried tomatoes are the game-changer here—oil-packed ones have the best flavor, but any brand works if you drain them well. Trader Joe's and Whole Foods carry the best quality, but the regular grocery store usually has decent options too. Look for ones that aren't too dry or shriveled. The sharp cheddar is non-negotiable—Kraft 2% Milk Sharp or Cabot are my go-tos, but any extra-sharp will do. Freshly grated Parmesan for the topping makes all the difference too—pre-grated gets clumpy and loses flavor fast.
No sun-dried tomatoes? Dried cherry tomatoes at half the amount work in a pinch, but they're less concentrated. Short on sharp cheddar? Monterey Jack or pepper jack adds a nice twist. The heavy cream can be swapped for half-and-half if you're watching fat, but trust me on the full-fat version—it's worth it. For the breadcrumbs, panko gives the best texture, but regular breadcrumbs toasted in butter work too. The garlic and onion can be pre-minced from a jar if you're short on time, but fresh is always better.
This reheats beautifully—honestly tastes better the next day once everything melds together. Keeps in the fridge for 4-5 days sealed tightly, or freeze portions for up to 3 months. I like to make a big batch on Sundays so I have leftovers for quick lunches during the week. The topping stays crispy if you reheat it covered with foil first, then uncover to crisp up the last 2 minutes.
Why You'll Love This Recipe
- One-Pot Magic: I swear by this—just toss everything in one dish, bake, and walk away. No boiling pasta separately, no straining, no extra pots. The sun-dried tomatoes melt right into that creamy cheddar sauce, and honestly? It’s the kind of meal where you can set the timer and still have time to actually eat it.
- Sun-Dried Tomato Twist: That salty, tangy pop from the sun-dried tomatoes cuts through the richness of the cheese. It’s not just mac and cheese—it’s like a little Italian vacation in every bite, and the sharp cheddar makes sure it’s never boring. (Yes, even on a Tuesday night.)
- Leftovers That Don’t Suck: Between us, most baked mac and cheese gets sad the second day. Not this one. The tomatoes keep it bright, and the crispy top? Still chef’s kiss reheated. I make a double batch on Sundays because it’s the only comfort food that tastes just as good cold for lunch the next day.
- Budget Comfort Food: Sharp cheddar and elbow mac are already cheap, but adding sun-dried tomatoes makes it feel fancy without breaking the bank. Heavy cream and milk are pantry staples, and you’ll use them up before they go bad. It’s the kind of dish that makes you feel like you’re treating yourself—without actually spending much.
Step-by-step instructions for baked mac and cheese with tomatoes
Here's how to create this decadent, sun-dried tomato-infused mac and cheese that's creamy, crispy, and packed with bold flavor.
🍳 Step 1: Cook the Pasta Al Dente
Bring a large pot of water to a rolling boil and add 1.5 lbs elbow macaroni. Stir immediately to prevent sticking. Cook until just shy of the package's al dente time—you want it to finish cooking in the oven. Reserve 1 cup of the pasta water before draining, as this starchy liquid is essential for a silky sauce.
I always drain the pasta well in a colander, then shake it gently to remove excess water. This ensures your sauce clings beautifully to each strand. Don't rinse the pasta—those surface starches help create that velvety texture we're after.
🍳 Step 2: Build the Sun-Dried Tomato Cream Sauce
In a large skillet, melt 0.5 cup butter over medium heat. Add the diced yellow onion and cook for 5 minutes until softened. Add the minced garlic cloves and cook for another 30 seconds until fragrant.
Reduce heat to low and whisk in the 2 tbsp all-purpose flour, cooking for 1 minute to remove the raw flour taste. Gradually pour in the 1.5 cups heavy cream and 0.5 cup whole milk, whisking constantly until smooth. Stir in the 0.5 cup chopped sun-dried tomatoes, 0.5 tsp dried thyme, 1.5 tsp salt, and 0.5 tsp ground black pepper.
🍳 Step 3: Combine Pasta and Cheese Mixture
Add the drained pasta to the sauce and stir well to coat. In a separate bowl, combine the 2 cups shredded sharp cheddar cheese with the pasta mixture. The heat from the pasta will begin melting the cheese immediately, creating that irresistible stretch.
If the mixture seems too thick, add reserved pasta water 1 tablespoon at a time until you reach a smooth, creamy consistency that coats the back of a spoon. Here's the thing—don't rush this step. Let the cheese melt completely before moving to the baking dish.
🥘 Step 4: Assemble and Bake to Perfection
Transfer the mac and cheese to a greased 9x13-inch baking dish. In a small bowl, mix together the 0.5 cup panko breadcrumbs and 0.25 cup grated parmesan cheese. Sprinkle this mixture evenly over the top of the mac and cheese.
Bake at 375°F for 25-30 minutes until the top is golden brown and bubbly. The edges should be crispy while the center remains creamy. If the top browns too quickly, tent loosely with aluminum foil for the last 5-10 minutes of baking.
⏰ Step 5: Rest and Serve Warm
Remove from the oven and let rest for 5-10 minutes before serving. This resting period allows the cheese to set slightly, making it easier to cut and preventing a runny mess. The crispy breadcrumb topping will be perfectly golden and crunchy.
Serve immediately with a simple green salad or crusty bread. Each bite delivers that perfect combination of creamy, cheesy goodness with the bright, tangy kick of sun-dried tomatoes. Trust me, this is one mac and cheese that will have everyone asking for seconds!
Pro Tips For Making Baked Mac And Cheese With Tomatoes
- PRE-COOK PASTA AL DENTE: Boil elbows until they’re just firm—about 1 minute less than package instructions. The extra starch in undercooked pasta binds the cheese sauce better, and they’ll finish cooking in the oven without turning mushy. I learned this the hard way after serving a batch that fell apart like wet cardboard.
- GRATE CHEESE FINE: Skip the food processor—sharp cheddar needs to melt smoothly, and pre-shredded cheese (with anti-caking agents) behaves like glue. Use a box grater and pulse in a food processor only if you’re impatient, but even then, avoid over-processing or it’ll turn rubbery. Your future self will notice the difference in texture.
- SAUCE FIRST, THEN TOMATOES: Build the cheese sauce with heavy cream and milk before adding sun-dried tomatoes—otherwise, you’ll end up with a watery, uneven mix. Rehydrate the tomatoes in a splash of pasta water first, then stir them in last. This keeps their flavor concentrated and prevents the sauce from breaking.
- BAKE COVERED, THEN CRUST: Start with foil over the dish for 20 minutes to melt the cheese evenly, then uncover and broil for 2–3 minutes. The foil step guarantees a creamy center, while the broil gives that golden, slightly crispy top—without burning the tomatoes underneath. I was skeptical until I tried it, and now it’s non-negotiable.
Dietary considerations for this recipe
Gluten-Free Adaptation
For a gluten-free version, swap elbow macaroni for gluten-free pasta like Barilla Gluten-Free or De Cecco Gluten-Free—both hold up well in baking. Use cornstarch or arrowroot powder (instead of flour) to thicken the sauce, mixing 2 tbsp into the melted butter before adding liquids.
The texture stays creamy, but the topping requires adjustment: replace panko with crushed gluten-free crackers or toasted gluten-free breadcrumbs for crispiness. 🥗
Dairy-Free Options
Replace heavy cream with full-fat coconut milk (canned, not carton) for richness, and use nutritional yeast (instead of Parmesan) for a cheesy flavor. For the cheddar, try dairy-free sharp cheddar shreds like Violife or Miyoko's.
Warm the coconut milk before adding to prevent curdling. The sun-dried tomatoes still shine, but the texture becomes slightly lighter—balance with extra 1 tbsp cornstarch for thickness.
Lower-Carb Modifications
Cut carbs by using shirataki noodles (rinsed well) or cauliflower rice (sautéed first). Reduce the pasta to 1 lb and stretch the dish with extra sun-dried tomatoes and roasted zucchini for volume.
For the sauce, use half the heavy cream and replace the rest with unsweetened almond milk to keep it lighter. The result is a creamy, tomato-forward casserole with fewer carbs but maximum flavor.
Vegan Version
Transform this into a vegan dish by using vegan sharp cheddar (like Daiya) and cashew cream (soak 1 cup cashews in water overnight, then blend with 1 cup water and 2 tbsp lemon juice). Replace butter with olive oil, and thicken with 1 tbsp cornstarch.
The sun-dried tomatoes add depth, but the sauce benefits from a splash of vegan Worcestershire sauce (about 1 tsp) for umami. Top with crushed gluten-free crackers for texture.
Allergen-Friendly Tips
For nut allergies, ensure all cheeses and breadcrumbs are nut-free (check labels—some Parmesan blends contain almond flour). If avoiding gluten and dairy, use certified gluten-free, dairy-free cheeses and quinoa pasta for a protein boost.
Always double-check labels, as cross-contamination is common in shared facilities. Keep the sun-dried tomatoes oil-packed (not in olive oil blends with other allergens) for safety. 💡

Frequently asked questions
Can I use fresh tomatoes instead of sun-dried?
Fresh tomatoes work but require different prep! Use 1 cup diced Roma tomatoes and roast them at 400°F for 15 minutes before adding to the sauce. This concentrates their flavor. Add 1 tsp sugar to balance acidity if needed. Fresh tomatoes add moisture, so reduce milk by 2 tbsp to maintain creaminess.
Why did my mac and cheese turn out dry?
This usually happens from overbaking or not enough liquid. First, check your baking time—25-30 minutes at 375°F is perfect. If it's still dry, try adding 2 tbsp milk or cream before baking next time. For extra insurance, tent with foil after 20 minutes to prevent over-browning.
Can I make this ahead of time?
This dish actually tastes better the next day. Assemble the casserole up to 24 hours ahead and refrigerate uncovered. When ready to bake, add 5-10 minutes to the baking time (cover with foil if needed). For freezing, bake first, then cool completely before wrapping tightly. Freeze for up to 3 months—reheat covered at 350°F for 30-40 minutes.
What's the best way to reheat leftovers?
For perfect texture, cover with foil and reheat at 350°F for 15-20 minutes until warmed through. Remove foil for the last 2 minutes to crisp the topping. Microwave method: Cover with a damp paper towel and heat in 30-second intervals until hot. The breadcrumb topping may soften slightly—broil for 1-2 minutes afterward to restore crispiness.
How can I make this spicier?
Add heat with 1/2 tsp cayenne pepper or 1 tsp smoked paprika to the cheese sauce. For deeper flavor, stir in 1/4 cup cooked chorizo (crumbled) or 1 tsp hot sauce**. Top with extra black pepper and a sprinkle of crispy bacon bits before baking. Roasted red peppers also add smoky heat while keeping the tomato flavor bright.
