Italian Sausage Pasta Bake

The basil goes on after the oven, not before. Twenty minutes at 400°F would blacken it, and the finished dish shows it green.

How Recipesdarleen publishes recipes

Nine ingredients and fifty-five minutes. This is a bake that gets its character from doing three simple things properly: browning the sausage, undercooking the pasta, and letting the cheese brown in patches rather than into a uniform lid.

The rigatoni comes out of the water two minutes shy of al dente. It has twenty minutes in a hot oven ahead of it, and pasta cooked fully before a bake comes out soft.

Why This Recipe Works

  • Browning the sausage to 160 degrees Fahrenheit before the sauce means the fond it leaves goes into the marinara.
  • Thirty seconds of garlic after the sausage is enough; any longer in a hot pan and it turns bitter.
  • Undercooking the rigatoni leaves it room to absorb sauce during the bake.
  • Twenty minutes at 400 degrees Fahrenheit browns the mozzarella in patches, which is what the finished dish shows.

Ingredient Notes

Italian sausage
A pound, casings removed and browned into crumbles to 160 degrees Fahrenheit.
Rigatoni
Twelve ounces, cooked two minutes short. The ridged tube is what holds the sauce in a bake.
Fresh basil
Half a cup of leaves, added after the oven. In it, they would blacken.

How to Make It

  1. Brown the sausage to 160F

    Heat oven to 400 degrees Fahrenheit. Brown sausage in oil until it reaches 160 degrees Fahrenheit; add garlic for 30 seconds.

  2. Make it a sauce

    Stir in marinara and red pepper flakes.

  3. Pasta, two minutes short

    Cook rigatoni 2 minutes shy of al dente and drain.

  4. Combine and top

    Combine pasta with sausage sauce, spread in a baking dish, and top with mozzarella and Parmesan.

  5. Bake, then basil

    Bake 20 minutes until bubbling and browned in patches; finish with fresh basil.

The Pan, the Pot, the Oven

Three short stages, and each one hands something deliberately unfinished to the next.

  1. Stage 1 of 3

    The pan - the sauce

    Steps 1–2 of 5

    Oven to 400F. 1 lb of Italian sausage browned out of its casings to 160F, then 3 garlic cloves for 30 seconds only, then a 24 oz jar of marinara and 1/2 tsp of red pepper flakes stirred into the fond.

    1. Brown the sausage to 160FHeat oven to 400 degrees Fahrenheit. Brown sausage in oil until it reaches 160 degrees Fahrenheit; add garlic for 30 seconds.
    2. Make it a sauceStir in marinara and red pepper flakes.
  2. Stage 2 of 3

    The pot - deliberately early

    Steps 3–3 of 5

    12 oz of rigatoni cooked 2 minutes shy of al dente and drained. It will look underdone, and it should: twenty minutes in a hot oven with sauce around it is still to come.

  3. Stage 3 of 3

    The oven - 20 minutes

    Steps 4–5 of 5

    Pasta combined with the sausage sauce, spread in a baking dish, 2 cups of mozzarella and 1/2 cup of Parmesan over the top. Baked until bubbling and browned in PATCHES rather than evenly, then 1/2 cup of fresh basil added once it is out.

    2. Bake, then basilBake 20 minutes until bubbling and browned in patches; finish with fresh basil.

Success Tips

  • Break the sausage into crumbles as it browns rather than leaving it in lumps.
  • Pull the pasta early even though it looks underdone — the bake finishes it.
  • Look for browned patches rather than an even golden sheet; that is the finish the dish shows.

Serving Ideas

Eight servings straight from the baking dish, the rigatoni in red sauce with the sausage crumbles visible under patches of browned mozzarella and fresh basil.

Frequently Asked Questions

Can the basil go in before baking?

No. Twenty minutes at 400 degrees Fahrenheit blackens it; it goes on after.

Why undercook the rigatoni?

It absorbs sauce and finishes cooking during the twenty-minute bake.

How done should the sausage be?

160 degrees Fahrenheit, browned, before the marinara goes in.
