“This made a huge pot of macaroni loved by baby and grownups! Feels like a huge success to get those veggies in, in such an enjoyable way.” – Jessica A.
What kid doesn’t love mac and cheese? It’s creamy, comforting, and always a hit at the table. So why not give it a nutritious boost by blending in a bunch of veggies? This recipe packs in sweet potatoes, cauliflower, red bell pepper, and onion—all roasted for extra flavor—then blended into a smooth, cheesy sauce.
If your child isn’t a fan of seeing veggies on their plate, this is a great way to incorporate them without a battle. I don’t recommend hiding or sneaking in vegetables, but blending them into a familiar dish like mac and cheese is a great way to offer extra nutrition while they’re still learning to enjoy them.
Keep exposing them to whole veggies on the side, and over time, they’ll get more comfortable!

Key Ingredients
I am highlighting just the ones that need further explanation. The complete list is in the recipe card below.
- Sweet Potato – Adds creamy texture, a hint of sweetness, and that golden color kids love. It blends right into the sauce, no chunks in sight.
- Cauliflower – Super mild but adds bulk and creaminess without extra dairy. It’s one of my favorite veggie add-ins.
- Red Bell Pepper – A little sweet, a little bright, and packed with nutrients. It perks up the flavor and color.
- Yellow Onion – Roasting brings out its natural sweetness and adds a subtle, savory depth to the sauce.
- Dijon Mustard – Sounds odd, but trust me, it makes the cheese flavor pop without tasting like mustard. Just a little goes a long way.
- Cornstarch (or arrowroot) – Thickens the sauce just enough so it clings to every bite of pasta.
- Cheddar Cheese – Sharp cheddar has the best flavor payoff. You don’t need a ton to make the sauce taste rich and cheesy.
- Elbow Macaroni Pasta – Classic for a reason! The shape holds onto the sauce, and it’s easy for little ones to eat.
Substitutions & Variations
From pantry swaps to fun add-ins, here are a few ways to make this recipe your own:
- Vegetables – While you’re roasting, throw in extra veggies like carrots or zucchini for added nutrition. They blend seamlessly into the sauce! Swap sweet potato with butternut squash or carrots for a similar creamy texture. Use broccoli or zucchini in place of cauliflower for a different veggie blend. Add spinach or peas for extra nutrients and color.
- Use Any Cheese You Love – Cheddar is classic, but gouda, mozzarella, Monterey Jack, or even a little Parmesan can add depth of flavor.
- Make it dairy-free – Use plant-based milk (unsweetened, like oat or cashew) and dairy-free cheese or nutritional yeast for a vegan-friendly version. This vegan cashew pasta sauce is delicious too!
- Make it gluten-free – Use your favorite gluten-free pasta and be sure to choose arrowroot instead of cornstarch.
- Spice it up – For older kids or grown-ups, a pinch of smoked paprika or crushed red pepper adds a nice kick.
- Protein Boost Ideas – Stir in shredded chicken, white beans, or lentils for a more filling meal.
How to Make Hidden Veggie Mac and Cheese
Step 1: Roast the Vegetables – Preheat oven to 400°F (200°C). Toss sweet potato, cauliflower, onion, and red bell pepper with oil and season with salt. Spread on a baking sheet and roast for 30-35 minutes, until softened.
Step 2: Cook the Pasta – While the veggies roast, cook pasta according to package directions. Save 1 cup of pasta cooking water before draining.
Step 3: Blend the Sauce – Once the vegetables are done, transfer them to a blender. Add Dijon mustard, garlic powder, cornstarch, milk, and shredded cheese. Blend until smooth.
Step 4: Pour the sauce into the pot used for cooking pasta. Heat over medium-low, stirring until warmed through. Add the cooked pasta to the sauce and toss to coat. Use the reserved pasta water, a little at a time, to thin the sauce to your desired consistency.
Expert Tips
- Cook Vegetables Until Very Soft – Soft vegetables are key to achieving a smooth, creamy sauce. If they are even slightly firm, the sauce may turn out grainy instead of silky.
- Use Freshly Shredded Cheese – Pre-shredded cheese contains anti-caking agents that can affect how smoothly it melts. Shredding your own cheese results in a creamier sauce.
- Make It Ahead – You can roast the veggies in advance and store them in the fridge for up to 3 days. When ready, just blend and heat!
- Blend thoroughly. If your blender struggles with thicker sauces, add a splash more milk to get things moving.
- Save that pasta water! It’s the key to loosening up your sauce without making it watery. Add a little at a time until the sauce is just right.
- Don’t Overheat the Sauce – Keep the heat low when combining the sauce and cheese. High heat can cause the cheese to separate and become grainy.
Serving Suggestions
Here are a few ways to round out your veggie mac and cheese and make it even more satisfying:
- Add Protein – Stir in cooked shredded chicken, ground turkey, salmon, or even blended white beans for an extra protein boost. See chicken for babies for cooking tips and how to safely serve.
- Serve with a veggie side – Pair with roasted broccoli, green beans, or a simple salad for an easy, well-rounded dinner.
- Pack in a thermos – Perfect for school lunches. Warm it in the morning and pack in an insulated container. Want more ideas? Check out my list of 60 healthy school lunch ideas for kids.
- For younger toddlers – Spoon into a bowl and let it cool slightly. The soft texture makes it easy to chew and enjoy, as well as being full of nutrition for growing eaters.
Hidden Veggie Mac and Cheese FAQs
Store any leftovers in an airtight container in the fridge for up to 3-4 days.
While pasta can get a bit mushy after freezing, the sauce alone freezes well! Store in a freezer-safe container for up to 2 months. When ready to enjoy, thaw in the fridge overnight, then reheat with a splash of milk before mixing with fresh-cooked pasta
Stovetop: Warm over low heat, adding small splashes of milk or reserved pasta water to bring back the creamy texture. Stir frequently to prevent sticking.
Microwave: Heat in 30-second intervals, stirring in between, and add a little milk if the sauce thickens too much.
You can! Just roast them straight from frozen. No need to thaw. They may release a bit more moisture, but the flavor will still be great.
Yes! While elbows are classic and great for holding the sauce, any short pasta shape like shells, rotini, or penne will work well.
The vegetables blend into a smooth, creamy sauce that complements the cheese. The flavor is mild and balanced, making it appealing for both kids and adults.
Use enough liquid when blending, add reserved pasta water as needed, and avoid overheating the cheese. A high-speed blender also makes a big difference.

Hi! This recipe looks great – do you think the sauce would freeze well since it’s a pretty large portion?
Yes you can def freeze the sauce!
Can this be frozen and reheated?
Absolutely!
I’m just curious, has anyone tried adding cottage cheese for more protein? Or does that mess with the flavours/textures too much?
