Cajun-seared steak bites, cheese tortellini and blistered peppers baked in a smoked gouda garlic cream, finished with a golden cheese crust. A rich, filling dinner that feeds six from a modest amount of steak.
Drying the steak thoroughly before seasoning is the single biggest factor in getting a good crust. Any surface moisture will cause the meat to steam rather than brown.
Grate the mozzarella and pepper jack yourself if possible. Pre-shredded cheese is coated with starch to prevent clumping, which can make it melt with a slightly grainy texture.
Adding the steak at the end rather than baking it with the pasta keeps it tender. Beef left in the oven for the full bake time will overcook and turn firm.
Store leftovers in an airtight container in the refrigerator for 3 to 4 days. The sauce thickens considerably once chilled, so stir a splash of cream or milk into each portion before reheating in the microwave, or cover the dish with foil and warm at 325°F for 20 to 25 minutes.
To make ahead, assemble the pasta, peppers and sauce in the dish without the cheese topping, cool, cover tightly and refrigerate for up to 24 hours. Add the cheese and panko straight from the refrigerator, bake covered for 20 minutes and uncovered for 12 to 15 minutes more, then sear the steak fresh while the dish is in the oven.
Freezing is not recommended, as cream sauces separate when thawed and cooked tortellini becomes soft and grainy.
