Instructions

For the Béchamel-Ricotta Sauce

  1. In a medium saucepan, heat the butter until melted. Add the flour and whisk until smooth. Over medium heat, cook the roux 2-3 minutes. Slowly add the milk, whisking constantly.
  2. Cook ~5 minutes, stirring constantly, until thickened enough to coat the back of a spoon. Remove from the heat and set aside to cool a bit while you cook the pasta.

  3. Once ready to assemble the lasagna, whisk in ricotta, salt, egg, and herbs into the béchamel.

For the Lasagna

  1. Heat oven to 350F.

  2. Add 2 cups marinara sauce to the cooked sausage make a meat sauce. Set aside.

  3. Bring a large pot of water to a boil.

  4. Cook the noodles to al dente according to package directions. Drain and rinse briefly with cold water.
  5. Spread the remaining 1/2 cup marinara sauce in a lasagna dish. Layer 3 noodles, 1/3 of the meat sauce, 1/3 of the béchamel-ricotta sauce, and 1/4 of each cheese. Repeat twice. Finish with a final layer of pasta and the last 1/4 of each cheese.

  6. Bake uncovered at 350F until bubbly, about an hour. Tent with foil over top if the top starts to get too brown. Let stand 10 min before cutting.

Recipe Notes

Note, take care to watch this cook and when the top starts to darken, get some foil tented over to prevent burning.
