Mac and cheese is the ultimate comfort food, but the classic version can feel like a brick in your stomach — and it takes a roux, a separate pot, and a casserole dish. This lightened version skips all of that. Frozen diced butternut squash simmers right in the pot with the pasta, then gets mashed into the sauce so it’s creamy with far less cheese. Add savory ground turkey for protein, fresh sage for that fall flavor, and you get a cozy one-pot dinner that tastes indulgent without being heavy.
Why you’ll love it
- Lightened, not sad. Mashed butternut squash gives you a velvety sauce with a fraction of the cheese and butter — but it still tastes like real mac and cheese.
- One pot. The pasta cooks in the broth right alongside the squash and turkey. One pot to wash, one pot to love.
- ~30g protein per serving (estimated), thanks to lean ground turkey plus cheddar and Parmesan.
- Fall flavors. Butternut squash, sage, and a pinch of nutmeg make this taste like October in a bowl.
Ingredients
- 1 tbsp olive oil
- 1 lb ground turkey, 93% lean
- 1 small yellow onion, diced
- 3 cloves garlic, minced
- 1 tsp dried sage, or 1 tablespoon chopped fresh sage, plus fresh leaves for serving
- 1/2 tsp dried thyme
- 1/2 tsp kosher salt, plus more to taste
- 1/2 tsp black pepper
- 1/4 tsp ground nutmeg
- 12 oz frozen diced butternut squash
- 12 oz elbow macaroni, uncooked
- 3 cups low-sodium chicken broth
- 1 cup whole or 2% milk
- 1 1/2 cups shredded sharp cheddar cheese
- 1/4 cup grated Parmesan cheese
Equipment
A large deep skillet with lid (12-inch) or a Dutch oven, a wooden spoon or spatula, and a potato masher or a large fork.
Instructions
- Brown the turkey. Heat the olive oil in a large deep skillet or Dutch oven over medium-high heat. Add the ground turkey and cook, breaking it into crumbles, until no pink remains, about 6 minutes. Drain off any excess liquid.
- Soften the aromatics. Stir in the onion and cook until softened, about 3 minutes. Add the garlic, dried sage, thyme, salt, pepper, and nutmeg; cook 1 minute more, until fragrant.
- Add squash, pasta, and liquids. Stir in the frozen diced butternut squash (no need to thaw — frozen squash is the shortcut that keeps this at 30 minutes), the elbow macaroni, the chicken broth, and the milk. Scrape up any browned bits. Bring to a lively simmer.
- Simmer covered. Reduce the heat to medium-low, cover, and cook until the pasta is tender and the squash is very soft, about 10–12 minutes. Stir once halfway through. The mixture should look creamy and just slightly saucy.
- Mash the squash in. Uncover and use a potato masher or large fork to mash the squash right into the sauce, breaking it down into a velvety puree that thickens everything. A few small chunks are fine — this is rustic comfort food.
- Melt the cheese off the heat. Take the skillet OFF the heat. Stir in the cheddar a handful at a time until melted and smooth, then the Parmesan. Taste and adjust salt and pepper. Serve with fresh sage leaves on top.
Doneness cues: Turkey must reach 165°F internally (it will, well before the end — the long simmer guarantees it). The pasta is done when tender; the squash is done when it mashes easily under a fork. The sauce is right when it coats the elbows thickly — it will look slightly loose right off the heat and set as it stands.

Substitutions and tips
- Fresh butternut squash works but adds prep time — peel and dice 3 cups into small cubes and add 3–4 minutes to the simmer. Frozen is the 30-minute answer.
- Ground chicken or lean ground beef swap in 1:1. For beef, drain the fat well.
- Make it spicier: add 1/4 teaspoon cayenne or a pinch of red pepper flakes with the other spices.
- Gluten-free: use your favorite gluten-free elbows and check that the broth is certified gluten-free; simmer time may vary slightly.
- Don’t boil the cheese. Add the cheddar and Parmesan off the heat so the sauce stays silky instead of grainy.
Storage and reheating
Refrigerate leftovers within 2 hours in an airtight container for up to 4 days. Reheat in a skillet over medium-low heat with a splash of milk, stirring, until steaming (165°F) — the sauce loosens back up beautifully. Microwave works in 60-second bursts, stirring between. Freezes well for up to 3 months; thaw overnight in the fridge. The pasta softens slightly after freezing but the flavor holds.
Frequently asked questions
Can I use canned pumpkin instead of butternut squash? You can, but the flavor is less sweet and rich. Stir in 1 cup of pumpkin puree at step 5 instead of mashing — reduce the broth by 1/2 cup since there’s no squash to absorb it.
Why is my sauce grainy? The cheese went in while the pan was too hot. Always melt cheese off the heat and add it a handful at a time, stirring until smooth before adding more.
Is this good for meal prep? Very — portion into containers for lunches all week. It reheats well with a splash of milk.
Can I make it vegetarian? Yes — skip the turkey and use vegetable broth. Add a can of drained white beans for protein.
How do I keep it from getting dry? The pot should look a little saucy when you take it off the heat; the pasta keeps absorbing liquid as it stands. A splash of milk when reheating fixes it completely.
