- Bacon or pancetta (6 strips, or 1/2 oz pancetta), cooked until crisp
- Red bell peppers (1, diced)
Sauce (Gratinata)

- Chicken broth (1/2 cup)
- Dijon mustard (1/2 tsp)
- Salt (1/2 tsp, plus more to taste)

- Mozzarella cheese (1 cup, shredded)

- Fresh rosemary (for garnish)
Ingredient Substitution Table
| Ingredient | Substitution |
|---|---|
| Marsala Wine | Apple Juice + Red Wine Vinegar |
| Bacon | Pancetta |
| Heavy Cream | Half & Half (not as rich), or Dairy-free alternative (taste will differ) |
| Chicken Broth | Vegetable Broth |
| Fresh Rosemary | Dried Rosemary (use half as much) |
| Shrimp | Leave out (more chicken or more bacon for extra protein) |
Essential Tools & Equipment
- Large skillet or sauté pan (for sauce and proteins)
- Pasta pot (with lid or built-in strainer for easy draining)
- Frying pan (for crisping bacon or pancetta)
- Oven-safe casserole dish, 9×13 inch (for family style) or individual gratin dishes
- Sharp chef’s knife and cutting board
- Wooden spoon or silicone spatula
- Measuring cups and spoons
- Whisk (for smooth gratinata sauce)
Step-by-Step Instructions
1. Prepare the Proteins
- Marinate chicken breasts overnight in olive oil and garlic salt if possible. Grill until cooked through, then slice into bite-size pieces. (You can substitute pan-searing if grilling is unavailable.)
- Peel and devein the shrimp, if using. Keep chilled until ready to sauté.
- Cook bacon or pancetta in a frying pan over medium heat until crisp. Drain and chop into small pieces.
2. Make the Gratinata Sauce
- In a large skillet over medium heat, sauté garlic and butter until just fragrant (do not brown).
- Pour in Marsala wine OR apple juice plus red wine vinegar, and simmer to reduce by one-third. Add chicken broth to equal about 1/3 cup combined liquid.
- Add Dijon mustard, salt, chopped rosemary, and cayenne pepper. Stir to combine.
- Pour in heavy cream and reduce heat, letting the sauce gently simmer (do not let it boil) until thickened and reduced, about 10-15 minutes, stirring often.
- Taste and adjust seasoning. The sauce should be creamy, tangy, and fragrant with rosemary.
3. Cook the Pasta
- Cook penne pasta in generously salted boiling water to al dente—just a minute or two before fully tender. Drain and set aside. (Avoid overcooking; pasta will soften more in the oven.)
4. Sauté Shrimp and Bell Peppers
- In a large skillet, melt 1 tbsp butter. Add shrimp and cook until just turning pink but still tender, about 2 minutes. Remove and set aside.
- In the same pan, sauté diced red bell peppers until slightly softened. (Add shallots for extra depth, if desired.)
5. Assemble the Penne Rustica
- In a large mixing bowl, combine cooked penne, chicken, shrimp, crisped bacon, and bell peppers.
- Stir in most of the gratinata sauce. Add parmesan cheese (about 1/3 cup), and toss to evenly coat ingredients.
- Spoon mixture into a greased 9×13″ casserole dish or into individual gratin dishes for restaurant-style presentation.
- Drizzle any remaining sauce evenly over the top.
6. Finish and Bake
- Top with shredded mozzarella and additional parmesan cheese.
- Sprinkle paprika for color and flavor, then garnish with chopped fresh rosemary.
- Bake at 475°F (246°C) for 10-12 minutes, or until the top is bubbly and beginning to brown.
- Remove and let rest 5 minutes before serving for best texture and flavor.
Tips, Variations, and Make-Ahead Options
Pro Tips for Restaurant-Quality Results
- Do not overcook the pasta. Penne should be “al dente” so it holds up after baking and absorbs some of the sauce.
- Use fresh rosemary for greater aromatic depth. If using dried rosemary, use half the amount.
- If using shrimp, add them just before baking to avoid overcooking.
Fun Variations
- Shrimp-Free: Omit shrimp for those with allergies or aversions, or double the chicken for extra protein.
- Add Vegetables: Roasted mushrooms, zucchini, or sun-dried tomatoes lend new flavors.
- Prosciutto: Substitute bacon/pancetta with smoked prosciutto for a silkier, smokier note.
- Make it Lighter: Use half-and-half instead of cream (the sauce will be less rich and thick), or reduce the amount of cheese for fewer calories.
Make-Ahead and Storage
- Prepare in Advance: Grill chicken, sauté shrimp, and make the sauce a day ahead. Cook pasta and store all components separately. When ready to eat, combine in baking dish, top with cheese, and bake as directed.
- Refrigerate: Leftovers keep well up to 3 days, covered, in the fridge. Reheat gently in the oven at 350°F; add a splash of cream if the sauce looks dry.
- Freeze (Before Baking): Assemble unbaked casserole, cover tightly, and freeze up to 2 months. Thaw overnight before baking.
Serving Suggestions
- Pair Penne Rustica with a simple green salad and a light vinaigrette.
- Serve with warm, crusty bread (such as a ciabatta or garlic loaf).
- A crisp, chilled white wine (Pinot Grigio or Sauvignon Blanc) or a sparkling mineral water complements the creamy sauce.
- Finish the meal with a light citrusy dessert (like lemon sorbet or cheesecake bars).
Frequently Asked Questions (FAQs)
Q: Can I make Penne Rustica without shrimp or bacon?
A: Absolutely! The recipe is flexible. Omit shrimp and/or bacon based on preference or dietary needs without sacrificing the integrity of the dish. Substitute double chicken or add veggies for balance.
Q: Is it possible to make this dish gluten-free?
A: Yes. Substitute your favorite gluten-free penne pasta and ensure all other ingredients (e.g., broth and mustard) are certified gluten-free.
Q: Can I use other pasta shapes?
A: You can use rigatoni, ziti, or fusilli. The goal is a shape that holds sauce well and retains texture after baking.
Q: How do I avoid a thin sauce?
A: Let the gratinata sauce simmer gently and reduce by about one-third before adding it to the dish. If it’s too thin after mixing, return to heat and simmer a few minutes more, stirring often.
Q: Can I prepare this dish in individual servings?
A: For a restaurant experience, divide the mixture among individual gratin dishes before topping and baking. This ensures a perfectly browned top for each portion.
Q: What if I can’t find fresh rosemary?
A: Dried rosemary works; use about half the amount and crush it between your fingers to release its oils before adding to the sauce.
Q: Can I make Penne Rustica ahead for a party?
A: Yes. Assemble the dish (without baking), cover, and refrigerate up to 24 hours. Add 5 extra minutes to baking time if cold from fridge.
