Can I use frozen tortellini?
Yes. Cook according to the package directions. Frozen tortellini usually takes longer than refrigerated, but brands vary. Start checking 1 to 2 minutes before the suggested time. A lot of tortellini will float when it is close, but doneness is “tender when you bite it,” not just “it surfaced.” Reserve pasta water like your life depends on it.
What can I substitute for pancetta?
Thick-cut bacon works great. For a lighter option, use chopped rotisserie chicken and add it when you toss the tortellini into the sauce. For vegetarian, skip the meat and add a pinch of smoked paprika plus extra Parmesan.
My sauce got too thick. How do I fix it?
Add reserved pasta water 1 tablespoon at a time while tossing over low heat until it turns silky again. Pasta water is the secret handshake.
My sauce looks separated. Did I ruin it?
Probably not. This often happens if the pan is too hot. Lower the heat and whisk in a splash of cream or milk. If it still will not come back together, take the pan off the heat, add a bit more cream, and whisk again. Gentle heat and patience usually fix it.
Can I make this spicy?
Absolutely. Add 1/4 to 1/2 teaspoon crushed red pepper with the garlic, or finish with Calabrian chili paste for deeper heat.
Is this recipe kid-friendly?
Yes. If you have picky eaters, keep the spinach chopped fine and go light on the red pepper flakes. The sauce is creamy and familiar, just more interesting.
How long does tortellini take to cook?
Follow the package. As a general guide, refrigerated tortellini is often 2 to 4 minutes, frozen is often 4 to 7 minutes.
