This isn’t your nonna’s heavy, cheese-laden casserole. We keep it balanced with lean turkey sausage, whole-grain pasta, and a ton of veggies. The secret?
Roasting the vegetables first for maximum flavor. And yes, there’s cheese—just not enough to clog your arteries. It’s a one-pan wonder that’s weeknight-friendly and meal-prep gold.
Ingredients You’ll Need
- 1 lb lean turkey sausage (or chicken sausage for extra flavor)
- 2 cups whole-grain penne pasta (or gluten-free if needed)
- 1 zucchini, diced
- 1 bell pepper, sliced
- 1 cup mushrooms, chopped
- 1 jar (24 oz) marinara sauce (sugar-free, because we’re not monsters)
- 1 cup part-skim mozzarella (because we’re not savages)
- 2 tbsp olive oil
- 1 tsp garlic powder
- Salt and pepper to taste
Step-by-Step Instructions

- Preheat your oven to 375°F. Because cold ovens are for storing shoes.
- Cook the pasta al dente. Drain and set aside.
Mushy pasta is a crime.
- Brown the sausage in a skillet. Break it up like it owes you money.
- Toss the veggies with olive oil, garlic powder, salt, and pepper. Roast for 15 minutes until they’re slightly charred.
- Mix pasta, sausage, veggies, and marinara in a casserole dish. Top with mozzarella because duh.
- Bake for 20 minutes. Finish with a broil for that crispy cheese crown.
How to Store This Masterpiece
Let it cool, then cover tightly or portion into meal-prep containers. Fridge: 3–4 days. Freezer: Up to 3 months (though let’s be real, it won’t last that long).
Reheat in the oven or microwave—just don’t nuke it into oblivion.
Why This Recipe Is a Win

discover exactly how to eat in a way that BOOSTS your metabolism, balances hormones, FIGHTS stubborn belly fat, heals your gut, and increases your energy, regardless of your "bad genetics".
It’s packed with protein, fiber, and veggies, so you’ll actually feel full without the regret. The whole-grain pasta keeps blood sugar steady, and roasting the veggies? That’s flavor without the extra oil.
Plus, it’s customizable—swap ingredients based on what’s in your fridge. Dinner shouldn’t be complicated.
Common Mistakes to Avoid
- Overcooking the pasta. It’ll turn to mush in the oven. Al dente or bust.
- Skipping the veggie roast. Raw veggies = sad, watery casserole.
- Using sugary marinara. Check labels.
You’re not making dessert.
- Drowning it in cheese. A little goes a long way. This isn’t a cheese pull contest.
Swaps and Substitutions
No turkey sausage? Use ground chicken or even lentils for a vegetarian twist.
Hate zucchini? Eggplant works. Dairy-free?
Swap mozzarella for a plant-based alternative (just don’t tell the Italians). The point? Make it work for you.
FAQs
Can I make this ahead of time?
Absolutely.
Assemble the casserole, cover, and refrigerate overnight. Bake as directed—just add 5–10 extra minutes if it’s cold from the fridge.
Is this recipe keto-friendly?
Almost. Swap the pasta for zucchini noodles or cauliflower rice, and you’re golden.
Can I freeze leftovers?
Yes, but the texture might change slightly.
Pro tip: Freeze individual portions for easy reheating.
What’s the best cheese to use?
Part-skim mozzarella melts well without too much grease. Want more flavor? Add a sprinkle of Parmesan.
Just don’t go overboard.
